Cell C Contract - Never Again

I had a contract with cell C and my last month of the contract was the first week in March 2024. The entire month of Jan I had cell C calling me like crazy to renew my contract but all of them that called me just wanted a sale but was of no help. When I asked for it to be canceled they would transfer me to the collections dept It's like when they transfer your call to the collections department they transfer it to a null and void number. I was advised that I need to call 1 month before to cancel my contract, everytime I tried calling them from early Feb 2024 their consultants were either directing the call to the incorrect department or the call was being dropped. I would try everyday and there would be no answer. Eventually I was very frustrated I sent an email, how ironic a consultant calls me back in the week of the 19 Feb 2024. I explained that I was trying to reach them 1 week ago to cancel my contract leaving out the times in Jan whereby the consultants that called were of no help. She very straight forwardly said unfortunately because the contract was not canceled one month in advance then she is canceling now 21 Feb 2024 and I have to pay for the month of March, they will load my services and I must use it by the 27 March becuase on the 27 March they will debut. They terminated my services on the 20 March so I didn't get to use my services remaining. She totally forgot the part whereby I mentioned I have been trying to do this for over a month. At that stage I was even bothered about the services I lost out on I then asked for a paid up letter and she advised "I" must call cell C on the 26 March and request it. There is not a abit of joy you will get from Cell C you can never get through to their contract department so I sent an email. They keep closing the tickets with me but has not given me feedback on anything. I tried calling yesterday and the consultant advised that the case is sitting with the collections department. So she transferred me to the collections department, I was holding for 36mins before I cut the call because no one picked up. Right now all I am waiting for is a Paid up letter and nothing has been sent to me. The reason for me requesting this as a matter of urgency is because they can continue building interest on that contract and 2 years down line you hear you in arrears. I would never waste my time taking another contract with Cell C, it's like they purposely giving me the run around, I would like them to please send me that letter I requested.
