Does Telmex have a customer service email?

Yes, telmexsoluciona@telmex.com is the address that reaches Telmex. Email is slower than phone or chat where those exist, but it puts everything in writing, which matters for billing disputes and refunds.

How do I get a human at Telmex?

Lead with your account email and one specific request. Vague messages get routed to automated replies; a specific, referenced request usually reaches a person on the first pass. If a bot replies, respond to the same thread restating the request and asking for it to be escalated.

What if Telmex doesn't reply?

Follow up on the same thread after 7 days, a one-line nudge referencing the original date is enough. Still nothing after 14 days and money is involved? Dispute the charge with your card issuer; "no response from merchant" supports a chargeback on every major card network.

What to include so you only ask once

The account email Telmex knows you by, first line, not buried at the bottom.
One reference: order number, invoice ID, or the date and amount of the charge you’re writing about.
One clear ask, a single sentence stating the decision you want confirmed in writing. Multi-question emails get partial answers.
A deadline expectation: “please confirm within 7 days” converts a read into a reply.

Hi Telmex team,

I'm contacting you about the account under [your account email].

[One sentence: what happened and the decision you want, e.g. "My order #1234 arrived damaged and I'd like a replacement."]

Please confirm what you'll do by reply within 7 days.

Best,
[your name]

Common questions about contacting Telmex

Call Telmex customer service on **800 123 2222** (free from any phone in Mexico). From your Telmex landline you can dial ***2222**. Choose the option to speak with an advisor and ask for **cancelación**. You can also start the request in the **Mi Telmex** app or website (Más servicios → Administra tus servicios), or through the WhatsApp chat linked from telmex.com. Whichever route you use, you'll be asked for your 10-digit Telmex number and given a **folio de cancelación**. Keep it, because you need it to return the modem and to dispute any later charges.
