DISGUSTING SERVICE - I WANT MY MONEY

I had a contract with cell c and I was given a reference number to use whenever making deposit payments, in November 14th 2022, I made a payment of R700 and from there on they were supposed to deduct R270 in December and then the contract is over. I usually send pop after making the payment but this time around they kept saying they cant find it, this went on for more than 30 days. In November 2022 they deducted R455 and in December they deducted R708 with no explanation til to date why that amount was deducted. After the cancellation of the contract only then they found the pop and started the refund process which has been taking over 30 days too as they reply to my emails every after two weeks. I have sent them everything they requested but until now I haven't received my refund which includes the arrears they deducted due to their fault not seeing my payment using my reference number given to me by them, what is that reference for if they cant track it? Their service is pathetic with customer care agents who also dont seem to know what a reference number is, one of them being S.T****. I have had enough of cell c ******** me, I want my money in my account now. This has taken too long now . DISGUSTING SERVICE!!!!!!!
