Invoiced Prices Greater Than What Vodafone Turkey Initially Quoted

On July 3, 2023, at 23:22, I contacted Vodafone Turkey's customer service to cancel my tariff as I intended to switch to another GSM operator. However, they offered me a deal for 87 TL to convince me not to cancel, which included 750 minutes, 1000 SMS, and 13 GB of internet. In the following months, my bills came out to be 181 TL. For two months, I tried to resolve this issue by calling them. Initially, the customer representative explained that the first bill was higher due to a cancellation that occurred before the billing cut-off date, and the overpaid amount would be deducted in subsequent months. But when my bill remained high the next month, I called again on September 12, 2023, at 01:00. This time, the representative admitted it was a mistake, promised to fix the problem, and opened a ticket for it. I was supposed to receive a response within nine days. However, when I didn't hear back, I called again on the same day at 15:15. The first representative transferred me to an expert representative, who abruptly disconnected the call while I was explaining my issue. I called again, and this time, the representative claimed that I had changed my tariff options, resulting in a bill of 187 TL. But if my bill is 187 TL now, why was it 181 TL for two months previously? Why wasn't this mentioned during my earlier calls? I feel deceived and scammed by Vodafone. None of the customer representatives have resolved my issue; they all divert to different explanations. I have recorded all my conversations with the representatives on another phone, and I intend to take my problem to the Consumer Arbitration Committee on the first business day. It should not be so easy for companies to deceive people, and the pursuit of profit should not be at the expense of honesty. I have faith that in a country like Turkey, governed by the rule of law, justice will eventually prevail.
