My 1000 Mbit internet speed dropped to 100 Mbit—just one-tenth of what I’m paying for. When I called customer service, they claimed everything looked fine and didn’t offer any help. I submitted a complaint with a screenshot using their own speed test tool, but I never received a response. They openly advertise and sell 1000 Mbit service but only provide a fraction of it. Even their own speed test clearly shows the issue, yet you can’t convince customer support. Don’t waste your money hoping for faster internet. After I posted my complaint here, they called me two days in a row, though we couldn’t connect for various reasons. During those two days, the speed seemed to be fixed. But guess what—today the speed dropped again. Why? Because they made it look like the problem was solved just to close the complaint. This kind of treatment toward customers is unethical. On top of that, they’re not providing the service they promised and are trying to block complaint channels. If you can’t deliver the promised speed, then admit it and issue a refund. I’ve filed two complaints already. Both times, they temporarily fixed the speed and called me. As soon as the complaint was closed, the speed dropped again. What kind of company treats its customers like this? It feels like they’re mocking us.

Superonline 1000 Mbps Fiber Internet Service Does Not Match the Speed I Receive! I subscribe to Turkcell Superonline’s 1000 Mbps fiber internet service, but for months the actual speed I’ve been receiving fluctuates between 90–150 Mbps. Despite calling customer service multiple times, they keep insi...
I am a Turkcell Superonline Fiber internet user. Since my 200 Mbps subscription's contract period ended, I upgraded to 1000 Mbps by paying the price difference during the renewal. However, since the upgrade, I have not seen any change in my internet speed. When I call customer service, they claim I’...
My Superonline customer number is 73675***. I’m a Superonline fiber subscriber and had been using a 25 Mbps internet package until my contract ended. After watching their ads, I upgraded to the 1000 Mbps fiber plan. However, since my modem is Wi-Fi 5, I can’t benefit from the full 1000 Mbps speed. W...
I am extremely frustrated with the poor service I’ve been receiving. How many times do I need to report an issue or call customer service only to be met with empty promises and no real solutions? Superonline collects my payment every month without fail, but when it comes to providing the service I’m...
