Incorrect Billing on my account

Acc# ********** 8

The 1st issue was that in August when I paid my monthly premium, I was told that I owe an amount if R1500.00,I called multichoice only to be told that I was charged in advance till next year Feb Secondly I paid R314.00 for a family package on Saturday 30 September 2017,which is R235.00,I called because I wanted to upgrade only to be told I owed R170.00,the consultant wasn’t sure why,she was going to listen to voice calls and call me back which never happened,so I called back yesterday and was told that the money in question was because I was charged in advance for insurance. Thirdly today I called and was told I owed an amount of R112.00,can someone tell me what is going on!!!!

Your service is terrible,I have wasted so much airtime calling multichoice because my account is not in place.
