Dissatisfied customer

I have an account with multi choice for years but since Tuesday I have been an aggrieved customer who is not finding any joy from multichoice.on Saturday I downgrade to family package and joined show max all went well until I got a call from Jazzman who works for Multichoice and offered a contract of 24months on price lock of 380.He promised to send an sms confirmation of the contract to date I have not received anything.i phoned after discovering that they have closed show max and de activated my extra view I spoke to a lady called Lusanda no help together with the supervisor. I called again today I was put on hold forever no help.The call center is so noisy .Today I spoke to a guy called Sphiwe again no help.i even suspect he just put my phone aside.They promise to give feedback yesterday but nothing happened.i paid them 609.00 but they are claiming I owe them 973.20 I don't know it's for what.They are busy going into my account trying to debit what I don't owe them.i have spend over R300 on airtym calling them but I have not been assisted instead I have experienced the worst service ever
