Unfair billing of account

On the 14th of July 2021 I called Multichoice to inform them that my banking account has been blocked and that they cannot debit any money from that account. The gentlemen who assisted me then sent me an easy payment reference number that i can use to make a payment. On the same day 14 July 2021, at around 5pm I went to Shoprite and made a payment of R568.50 as advised on the SMS I received from Multi choice. Later that day I checked on the App and it indicated that I owe R0.00. My DSTV was never disconnected. On the 18 July 2021, when I checked the App it showed that I owe R734, same day I called Multichoice and I spoke to Ms. Slindile Ngwane who indicated that she is escalating the matter to finance department. Today 01 August 2021, I checked the App again and it indicated that I owe R1563. I called DSTV and I spoke to Ms. Ncamsile Mgwaba who also indicated that she will escalate the matter to Finance Department. I have never missed a payment. Can Multichoice explain what the R1563 is for, because i did pay for my premium at Shoprite for the month of July. My number is ***. no one should go to my account and deduct the money that i dont even know what is it for.
