I'm writing to express my extreme disappointment and frustration with the handling of my account

I'm writing to express my extreme disappointment and frustration with the handling of my account. I have been a loyal Cell C customer for over 15 years, but my recent experience has been unacceptable. My number was ported on the 01/07/2025 yet I am still being charged for a contract and benefits I can no longer use. No one from Cell C ever informed me that I would be held financially liable for the remainder of the contract. This is a significant omission of information that has led to a great deal of inconvenience. I have tried to be reasonable by asking if I could simply use a different number to get the benefits I am paying for. This request was supposedly escalated to a regional manager weeks ago, but I have not received a single update. This lack of communication and resolution is simply not good enough for a long-standing customer. I expect immediate action on this matter and a fair resolution.
