Cell C Accounts January R9321.77 February 25 R5000 then February 29 R7359.62

I am tired of cell c and them billing me for the following amounts, on 31 January 2020 R9321.77 on the 25 February 2020 R5000 on the 29 February R 7359.62. I contacted cell c when they debited my account for the first amount they logged the complaint and even called me but never resolved the account. I then reversed the first amount of R9321.77. The account was for GPRS and now I am once again dealing with the call center customer care who don't have a clue how to do there job and can not resolve the issue and I am tired of logging complaints with the center . I had a nice chap call me with the first time they took wait stole money from my account. cell c is a company that wants a good name but they are causing issues. I ask for the direct number to the accounts section of cell c and they don't have one. how am I supposed to solve the issue if I one cannot sit down at a store or on line speak to a person who actually listens to the customer and understands the customer is not stupid as well some of the customer care personnel think I am. I am also tired of being cut off or them calling me and I just hear music hold on music for a minute and then cut off. I even have been told the matter has been resolved NO NO NO NO NO NO NO If a cell C person calls me I just want to hear we are sorry no ******* and jargon bla bla bla give back my money and I wish to cancel my contract with you at no more money removed from me CELL C WORST WORST service
