Bad service

I took a price lock with multichoice in April 2019 didn't have a problem up until last month when they debited R1117, 00 instead of the agreed amount of R934 for a Premium package, and I have dual view, what I did was I called the bank and reverse the amount and on the same day ( 27th) September I made EFT to multichoice for the amount of R934, to my surprise on the 22nd October they suspended my account, I called multichoice & spoke to Nicole and explain the situation suspension lifted, next day 23rd account suspended again I called in again spoke to African guy he then said, according to their system I requested to downgrade to lower package, how can I downgrade if I have a contract for premium?, he then remove the error and it came back on again, today 24th when I switch on the TV same message pop up iam suspended due to non payment I called in the first consultant I spoke to was unhelpful, and rude, I tried again, and again for the third time I spoke to Zandile, explain the reason for this call she then said she needs to speak to her supervisor like everybody else after long wait eventually she came back she tried this time my primary Decoder is on but my secondary is not working she then said she will escalate I don't know to who it will be back in the next 20 minutes and the time now is 21:25 from 19:00 still not working still suspended reconnection payed account payed and tomorrow on the 25th, they will debit my account but I don't have a service, Multichoice did admit that they had a problem with their system of which customers were overcharged, but for that I have to suffer, this is the reference number I was given by Zandile, can someone who knows what is happening call me - reference number given today ***4/I161call me, cannot wait for the contract to be over
