Cleo customer service phone number — how to find, verify and use it

Overview: multiple “Cleo” brands and why accuracy matters

The name “Cleo” is used by several distinct companies — most commonly a consumer-facing fintech/chatbot app and an enterprise integration/EDI software vendor. Because of that, there is no single universal “Cleo customer service phone number.” Calling the wrong number can waste time or expose you to fraud, so the first step is identifying which legal entity you need to contact (consumer app vs. enterprise software vs. other local business named Cleo).

As an industry professional I recommend treating any initial phone number you find as provisional until you verify it against official documents: the vendor’s contract, the customer portal, a stamped invoice, or the company’s verified website and social profiles. That prevents misdirected calls, charge disputes and social-engineering attacks.

How to locate and verify the official Cleo customer service phone number

Start on the vendor’s official assets. For a consumer app, open the app, go to Help or Settings → Support; most consumer fintechs route support to in‑app chat or email and do not publish a public call center number. For enterprise Cleo products (integration, secure file transfer), check the enterprise customer portal, your signed statement of work (SOW) and the “Contact Us” page on the vendor’s verified domain (check the SSL lock and exact domain name).

Verify a candidate phone number with at least two independent sources: (1) your contract/invoice which should show the official support phone and escalation contacts; (2) the company’s Google Business Profile or LinkedIn company page with a verified badge; or (3) an official email address that matches the corporate domain (for example, [email protected]). If in doubt, request a call‑back through the portal rather than dialing a number you found in a web search result.

• Quick verification checklist: confirm domain SSL, match phone to contract/invoice, confirm via in‑app “Contact” page, check corporate LinkedIn/Google Business. Red flags: phone numbers on third‑party forums, requests to pay on a non‑contract payment link, or unsolicited SMS with a phone number.

What to expect when you call — channels, hours, and SLAs

Consumer Cleo support tends to prioritize in‑app chat and email; typical email response windows are 24–72 hours, with faster response for high‑severity issues. Phone support for consumer apps is increasingly rare; if a public phone number exists it is often for legacy or sales inquiries. Enterprise customers generally have phone-based 24×7 support tiers with SLAs: severity‑1 (production down) responses commonly target 1–4 hour acknowledgement and 4–24 hour remediation windows, depending on your contract.

Typical expectations to set with the agent: ask for a ticket number and expected SLA in hours, the name/title of the support engineer, and the escalation path (manager, account manager, CSM). If a phone wait is long, request a callback (provide best call-back number and a 30–60 minute window). Industry benchmarks: phone hold times vary widely but 5–20 minutes is a normal consumer range; enterprise premium support reduces that to under 10 minutes and often includes a dedicated phone bridge number.

If you can’t find a phone number: alternatives and escalation steps

If no verified phone contact exists, escalate through the official channels listed on invoices and the customer portal. For billing disputes, contact your bank or card issuer to initiate a dispute or chargeback only after attempting vendor resolution; keep dates and evidence ready. For unresolved consumer financial complaints in the U.S., you can also file with the Consumer Financial Protection Bureau (cfpb.gov) or use your country’s financial ombudsman (for example the Financial Ombudsman Service in the UK at financial-ombudsman.org.uk).

When escalation is necessary, document every interaction (date/time, agent name, ticket number, summary). If you need to publicize a problem to trigger action, post a concise message on verified social channels (Twitter/X, LinkedIn) but include only non‑sensitive facts — never post account numbers or screenshots containing full card numbers.

• What to have ready and sample script: gather account ID, last 4 of payment card, invoice/order number, exact timestamps (YYYY‑MM‑DD HH:MM TZ), screenshots of errors, and the support email/ticket you previously used. Sample opening line for the call or chat: “Hello — I’m [Full Name], customer ID [123456]. I’m calling about transaction ID [ABC123] dated 2025‑06‑15 for $49.99 that posted incorrectly. My ticket number is #98765. Can you acknowledge and escalate to severity‑2? I need an estimated resolution time.”

Security and fraud prevention when using phone support

Never give full card numbers, passwords, one‑time passwords (OTPs), or your device PIN over an unsolicited call. Legitimate support will never ask you to share a 6‑digit OTP they sent to your phone; if a caller asks for that, terminate the call and report it. If a representative needs to verify identity, ask them to provide the last four digits of a payment method on file and a reference from your most recent invoice — then confirm by initiating a portal-based callback.

If you’re transferred, request the full name and direct extension of the next agent and verify the call is still on the company’s official number (or ask them to call you back from the number listed in your contract). For persistent unresolved issues, request written confirmation of the agreed remediation steps and deadlines, and save that email as your formal record.
