Maven customer service number — comprehensive guide for finding and using support

Which “Maven” are you trying to reach?

The brand name Maven is used by several companies: Maven (GM) — a car-sharing and vehicle subscription service launched by General Motors in 2016; Maven Clinic — a telehealth and family-care platform founded around 2014; and niche software or consulting firms that include “Maven” in their name. Each organisation has a different customer service channel. Before searching for a phone number, identify the product or contract you have (car rental, clinical appointment, employer benefit, project-management software) and the account or reservation ID tied to it.

If you are uncertain which Maven you used, check the confirmation email, your bank or credit-card statement for the merchant name, or the mobile app you used to book the service. The merchant name and the URL on the receipt (for example a domain that contains “maven” or a corporate parent like “general motors” or an employer benefits portal) will tell you which Maven to contact and therefore which customer-service number to use.

How to find and verify the official customer service number

The single safest rule: only use phone numbers published on the company’s official channels. Priority order: the mobile app’s Help/Support screen, the company’s official website (HTTPS with a valid certificate), the confirmation or invoice email you received, or the employer/benefits portal if Maven Clinic was provided through work. Avoid third‑party directories unless you can cross‑check the number on the official site.

When you find a number, verify it quickly: call during weekday business hours and ask the agent to state their name, department, and corporate address for your records. If you are given an alternate contact (a case number or escalation line), write it down and confirm the expected SLA (hours until first response and total resolution time).

Quick verification checklist

• Confirm domain and HTTPS: the support page should be on the provider’s official domain (e.g., the app link or a domain you recognize) and show a secure padlock in the browser address bar.
• Cross-check the number in the confirmation email, contract, or app — these are authoritative and usually include a dedicated support line or in-app messaging link.
• Look for a verified social-media account (blue check) and compare the contact details posted there with the website; reputable companies will not publish two different primary support numbers without explanation.

What to prepare before you call

Being prepared reduces call time and speeds resolution. Have these items immediately available: reservation/appointment ID, full name on the account, email on file, last four digits of the payment card, vehicle plate or VIN for mobility services, date/time of incident, screenshots of error messages, and a clear desired outcome (refund, credit, rebooking, clinic reschedule). If your issue involves charges, have the exact amount and the date as shown on your statement.

Document the call: note the date/time you called, the agent’s name and ID, the case number they create, and any promised deadlines. If you have one, use a second device to record the call only where it is legal; otherwise, take detailed notes. If the issue is time-sensitive (vehicle stranded, safety concern), call and then follow up immediately in writing (email or in-app message) so there is an auditable trace.

Essential items to have ready

• Account identifiers: email on file, phone number on file, account/reservation/appointment IDs.
• Billing evidence: screenshot of disputed charge, date/time, and the exact amount (currency and cents).
• Operational details: vehicle make/model and plate or clinic appointment date/time and clinician name where applicable; clear photos if damage or condition is the issue.

Typical response times, hours and best-case expectations

Most consumer-facing services publish their expected SLA: phone lines often operate Monday–Friday 8:00–20:00 local time, with emergency or roadside support available 24/7 for mobility incidents. Email and in-app messaging commonly promise an initial reply within 24–72 hours; live chat and phone exchanges typically resolve basic issues in one interaction or create a ticket with a 3–7 business‑day resolution window for complex refunds or investigations.

If your matter is urgent (safety, stranded vehicle, clinical emergency), demand escalation to an on‑call team and insist on a callback within the hour. If a promised callback or follow-up does not occur, escalate by asking for a supervisor, recording the broken SLA in writing, and setting a deadline for escalation (for example: “Please escalate to a manager if not resolved within 48 hours.”).

Escalation, dispute resolution and official complaint channels

If direct customer service does not resolve your issue, escalate by submitting a formal complaint via the company’s corporate email or legal address (listed in the Terms of Service). Keep all communications chronological and include supporting documents. If you used a credit or debit card, consider filing a dispute through your card issuer; most card companies have a 60–120 day window to contest a charge after the transaction date, depending on your issuer and the reason code.

External resources: file a complaint with the Better Business Bureau (www.bbb.org) for U.S. companies, or contact the Federal Trade Commission at 1‑877‑FTC‑HELP (1‑877‑382‑4357) and https://www.ftc.gov for consumer-protection assistance. For employment‑benefit disputes (Maven Clinic or employer-provided services), contact your HR/benefits administrator — they are the contractual purchaser and can often secure faster resolution.

Sample call script and follow-up email (practical template)

Call script (concise): “Hello, my name is [Full Name], account [email]. I’m calling about [reservation ID] from [date]. The issue is [concise statement: overcharge / vehicle damage / missed clinic appointment]. I would like [refund/rebooking/technical fix]. Do you have a case number and estimated time to resolution?” Record the agent’s response and confirm next steps before ending the call.

Follow-up email template (short): “Subject: Follow-up — Case #[case number] — [short issue]. Hello [Agent Name], Thank you for taking my call on [date]. Per our conversation, please confirm the agreed resolution and deadline. Attached: [screenshots/receipts]. I expect written confirmation within 48 hours. Regards, [Full Name, phone, account email].” Send this to the address the agent confirms and archive the sent message.
