Poor after service level

I would like to share in the horrible service that I have been getting from Cell C. End of June 2021 I had called cell customer service to cancel my contract and asked for the full amount of of the remaining balance so that I could pay the next day I paid the full amount and asked that the contract to be terminated as I could no longer afford to pay for a cell phone contract and did not want to upgrade cause budget is tight and economy is rough and true to my word I did so after not hear anything about the payment I called once again to check if payment went through and was ask for proof of payment of which I had provided. Please not of the past years I had a cell phone contract of which I paid for data I never used nor airtime I never used but was being charged for it anyways and I hardly complained. Today well a few minutes ago I get an sms notification from my bank for a Cell bill of R347. 01 what is it for as I had canceled the subscription all together I did not upgrade nor used the Sim card as that come with the phone was not working? Please an Cell C reimburse me my money it might just be R347. 01 but to me it goes a long way. You are reaping people off their hard earned money for what to be the same as the ruling government?. Please contact me on ***.i have kids, fees and bills to pay and that R347. 01qas allocated else where. I had made the call earlier and sent you the proof of payment but still yet you charged me for something that I had fully paid it says alot about your customer service and after service that you provided your customers which is really below poor. Please can someone urgently resolve this issue and reimburse me my money.
