Vodafone's Excessive Fees and Unfulfilled Offers

I have a Vodafone postpaid line and contacted customer service when my commitment period expired. They assured me that I would remain on the 150 TL plan. Given the current trend of price increases for everything, I double-checked to ensure that my bill would remain stable at 150 TL. I received a 186 TL bill at the end of the month. When I called customer service again, I mentioned the specific day and time of our conversation, and I was assured that the 150 TL charge would be waived. They apologized and promised to fix the problem. They resumed overcharging after a month of correction. I live in an earthquake-prone area, and my mental health didn't allow me to deal with it at the time, but my bill today shows 367 TL. This is unethical behavior on your part.
Progress
I am using a Vodafone postpaid line. When my commitment period ended, I contacted customer service, and they assured me that I would continue on the same tariff for 150 TL. However, when my bill arrived at the end of the month, it was 186 TL. I contacted customer service again, and they promised to fix it. They corrected it for one month, but then started overcharging again. I live in an earthquake-prone area, and during that time, my mental health did not allow me to deal with this issue, but today I saw that my bill is 354 TL. I created a complaint ticket, and the customer representative who called me said it's 200 TL, but the discrepancy is evident both in their mobile app and in the attached photo.
