Phone or internet contract — ΕΕΤΤ · Greece

Direct answer

Telecom providers have a legal complaints procedure with a deadline, and a regulator behind it. Complain to the provider in writing first — billing, speed far below the contract, a line down for days, a switch you never asked for. If they do not solve it within the deadline, ΕΕΤΤ — καταγγελίες καταναλωτών (801 11 000 33) — the telecom regulator or its dispute service for Greece — decides for free, and providers follow. Γενική Γραμματεία Καταναλωτή — 1520 (1520) helps with contract terms; Συνήγορος του Καταναλωτή (210 6460862) is the general dispute body if the case is about the sale rather than the service.

❓ Frequently asked

They switched me to a new plan without asking

Not allowed. Demand the old plan back in writing and complain to ΕΕΤΤ — καταγγελίες καταναλωτών; unrequested changes are a recurring enforcement topic.

Can I cancel because the speed is bad?

Yes, if there is a significant, continuous or regular discrepancy between the real and the contractual speed. Keep the measurements.

The outage lasted a week — compensation?

Many countries oblige a credit per day of outage after a report. Ask for it explicitly; providers rarely add it themselves.
