Eft payment

For the past few days I have had he worst experience ever with Multi choice,on the 20th of July I paid r818 that was due on my dstv account and on the 25th of July I got a message that my subscription has been cancelled,I then called the call centre and I spoke to 3 different ladies and they requested my proof of payment I then sent it to them to my surprise some of the channels were not working I then called the call Centre again only to find out that one the consultants downgraded my account which I never asked for I used the chatting platform the lady by the name of Kgomosto assisted me but to my surprise my balance due was now r96 because of the lady that downgraded my account without my consent and she said she will rectify it this morning I checked my balance and its showing iam owing r464,I have made numerous request to get the multi choice people to call me back but they promise me lies as always I cant pay soo much money via EFT and the prrof is there but still they keep on billing me wrong..please can I get this rectified
