There is no way I exceeded my internet usage during the specified dates. Unlike in the past, I did not receive any warning messages about my remaining data balance. During those days, I was either at home or at work, both of which have stable Wi-Fi connections, so I had no reason to use mobile data. I’ve been a loyal Turkcell customer for years, but I’m genuinely exhausted by these ongoing billing issues. I contacted your customer service, yet the problem is still unresolved. It feels like there’s a conflict of interest, with little to no real support for customers. I do not accept this charge and request a detailed report showing exactly when and where the internet was used—hour by hour, day by day—sent to my email. This is my right as a consumer. I never received a single notification saying I exceeded my data package. I refuse to pay for data I didn’t use. If necessary, you may cancel my line. These repeated errors are unacceptable. And during major emergencies like earthquakes or floods, we still experience connection problems. We, the users, keep paying the price, yet receive unreliable service in return.
In the last three months (June, July, and August), I have experienced a significant increase in my bill amount on my Turkcell postpaid line. Even though my internet usage had not run out, it appeared as if it had, and they continuously charged me for additional 1 GB packages, resulting in approximately 300 TL extra charges on each bill. However, I use Wi-Fi both at my workplace and at home, so it is impossible for my mobile internet to be depleted. Also, while I used to receive a warning SMS when my internet package was about to run out, I have not received any such notification in the past three months.
I have called customer service multiple times, and they told me that the internet was used by me and that warning messages should have been sent. However, I did not receive any warning SMS. I have experienced similar issues before and was forced to pay the extra charges.
I consider such practices to be similar to fraud, and I no longer want to be a victim. I request that all excess internet charges collected from me be refunded or deducted from my future bills. Additionally, I want an explanation as to why the warning SMS messages were not sent and for this grievance to be resolved.
Turkcell added over ₺400 to my bill, claiming that I exceeded my data limit eight times within just five minutes, despite not having my phone with me or actively using the internet. When I spoke to customer service, they dismissed me, saying they could not assist. The live chat support on the mobile...
As a customer who has happily used Turkcell for years and has generally been satisfied with the services provided, I now feel compelled to write this complaint due to a series of issues I've recently encountered. Lately, with significant increases in package prices and consistently high bills due to...
Each month, I receive payments from the Turkcell operator that are higher than my bill amount. I've reached out to customer service several times, clearly stating that I have not gone over any limits or made any extra purchases. Regardless of my objections, they insist on blaming me for lies, contin...
I switched to Turkcell with my line number 545280***49 on March 20. My first bill was issued on April 10, marking the end of the first month of my contract. The second bill was issued on May 10, completing the second month. Strangely, a billing cycle change request was made through the Turkcell app ...
I had been a long-time Turkcell user, but after my contract expired, I switched my mobile operator from Turkcell to Vodafone. I always paid my bills on time and expected a smooth transition after the contract ended. Unfortunately, at the end of my contract, Turkcell added an extra charge to my final...
