Very unprofessional and unreliable service. The technician failed to show up within the scheduled time window, and despite multiple calls and reassurances over nearly two months, the installation was never completed. Extremely poor communication and complete disregard for the customer’s time.

I paid for 100mbps for years and got "McDonalds" connection. Unstable with constant errors and "Have you tried to restart" ridiculous customer service that never solves anything. Their infrastructure is garbage. Their Antennas get a 100 errors a day. You can't watch a movie without interrupting it 20 times due to internet connectivity issues. Mobile connection away from Athens is garbage too. On top of that they are the most expensive. Horrible company. Checking my options to move on to a more decent provider. I feel like I'm giving them my hard earned money and they're giving me the finger. By the time I wrote this internet connection was interrupted 3 times lol

As Technology advisor for many companies

As Technology advisor this is in honest words a vulture company, there services are lacking in every aspect.phone lines for VoIP are expensive even though in operating cost is less for any company, there internet is the worst in the country of Greece with the services having half upload for 70% of their contracts even for companies/businesses. Even their business gifts are shit now, and most of their work force are just ex-public workers leeches holding on for life while doing nothing, most of their phone lines are now also either AI or an external company.

If you are in Greece

If you are in Greece, and you're contemplating getting a service proivder, AVOID Cosmote at all costs.They have zero customer service, deceiving tactics, such as promising services which you apply for and then never acting upon them (I have been waiting for the enabling of my new connection for the past 4 months now) and do not deserve your money. Literally try anything else, but heed - the servces in Greece are more akin a Mafia than real competetive companies.

Christmas "gift"

Their Christmas "gift" of unlimited data for 7 days only applies if you top up your phone and you get free data for the top up, so what's the point?? Always used this company but there are no incentives given for a user to keep using it. Also their mobile data connection is rubbish!!

Zero support and shady business

Zero support. Moreover the app can take your money you have parked in there for auto renew purposes, with no warning, never to be claimed again.Awful experience and Shady business.

Very bad experience

Worst provider with worst support at the time I write this 12/2025.Their site does anything to prevent you from accessing support, very misleading. Dead links, third party advertisements.

Even one star is to much

Even one star is to much, if you try to end your contract you can call what you want. Nobody can help you and they promise to call you back but they never do!! I have €60,- of phone costs and stil waiting for the call. A bunch of thieves that’s what they are!
