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 at all, and the 2.4G connection is both very slow and constantly disconnecting. Since we’re not home during the day, my spouse, children, and I usually use the internet in the evenings, and we all experience the same issues. I’ve reset the modem and Wi-Fi settings multiple times through online services and contacted customer support, who claimed to have made improvements, but nothing has changed. Customer service keeps saying there’s no issue visible in the system and offers no real solution. I’ve been using this modem for about three years, and there are 12 months left on my contract. I pay ₺530 every month but do not receive the service I’m paying for. I request a modem replacement and for my internet speed to be fixed. I simply want to get the quality I’m paying for and use the service without problems.

With only two days remaining on my contract, I did not want to go through the trouble of switching to another provider, so I accepted the...

On June 1, 2024, at 5:00 PM, I contacted Turkcell Superonline representatives at 0532**32 00 00 to upgrade our existing 100 Mbps internet speed to 200 Mbps. They upgraded it, but then completely cut off our internet. We tried calling 5-6 times afterward, but the calls were repeatedly disconnected wh...
There’s no internet with Superonline. Even though it was extremely difficult to reach the phone number supposedly assigned for reporting technical issues, they still didn’t provide a solution. Every step has been tried one by one. I even restarted the system multiple times and reset the modem, just ...
