Do you mean “TFC” as in The Filipino Channel (ABS-CBN/TFC), or a different organization named TFC (for example a finance or telecom company)? Also tell me which country/region you need the customer service number for (US, Canada, UK, UAE, Australia, Philippines, etc.) and whether you want phone only or a full customer-service guide (hours, email, online support links, common troubleshooting, billing & cancellation steps, prices, addresses).
Once you confirm, I will produce the detailed HTML text you requested (using h1–h3, p, and up to two packed ul lists) with accurate, region-specific phone numbers, addresses, websites, hours, pricing and practical instructions.
