Poor customer service

On the 26th of Oct l went on to the dstv app where l had thought of upgrading my dstv account upon doing so l ended up not doing it as l notice it was more or less the same options l would have just had the first time when they closed l called and and she said it was a billing error and she opened my account following week same issue happened again and same explanation was given. Yesterday l was on there chat and the person l chat to said nothing is owed and all is up to date. For the record l have never paid late my account is up to date later along am being told now l owe 193.00 but l paid for my account on the 25 Oct if Dstv no longer want me as a client they can just say so than them trying to ***** money
