Vodafone Customer Service Misinformation About Line Update and Compensation Request

As I'm a Vodafone user, I was reminded by customer service that my commitment was about to end. They quoted a price of ₺140 for the new term. On October 29, I called customer service again, expressing my interest in benefiting from the 2nd-term campaign. The lady on the phone stated it wasn't possible and promptly hung up. Following this, I requested to port my number to Turkcell. When the request reached Vodafone, I received a message stating I could continue with my plan for ₺61.12. I was misled due to incorrect information from Vodafone customer service, leaving me as the aggrieved party. I've made numerous calls, requesting the review of the call recordings, but a month has passed with no information provided. Upon calling again, they claimed the recording wasn't reviewed, and there was nothing they could do, exacerbating my distress. I seek compensation for the financial loss and hardship caused by their mistake. I also request to port my number back to Vodafone, continuing with the ₺61.12 offer they initially provided.
