I've been using Turkcell Superonline Fiber for about 10 months now. My package is supposed to provide 25 Mbps, but the actual internet speed I'm getting barely reaches 1.5-2 Mbps. While speed tests show no issues (as seen in the screenshot), the actual download speeds are terrible. Instead of 25 Mbps, I’m only getting 1.5-2 Mbps at most.
I contacted customer service, and they said that although my internet speed appears normal, there are issues with my signal causing frequent disconnections. They sent a technician who just pressed a button and left—no modem replacement, nothing. My issue remains unresolved, and I’m not even getting a quarter of the speed I should be receiving.
I'm tired of paying monthly bills to Turkcell for such poor service. Please resolve my issue immediately.

Despite calling customer service multiple times, they keep insi...

However, since the upgrade, I have not seen any change in my internet speed. When I call customer service, they claim I’...
Turkcell Superonline has not been able to provide internet service for 10 days. If this is what they call fiber speed, we're in trouble. I don't care about the issues with their subcontractor; that's their responsibility, not mine. We provided two phone numbers, yet they claim they couldn't reach us...
I am a Superonline user with the number 5320**12 and have been a Turkcell customer for about two to three years. For the past two to three months, I’ve been using a ZTE zxhn H267AV2 modem with a 50 Mbps internet service. Even though I’m in the same room as the modem, the 5G connection doesn’t work a...
