Month 4 and no resolution

So I have been complaining about so called data charges. I was told by call centre, Morningside Customer care and hello Peter response that my limit was 0. I am still get bills stating my limit is somehow R13755. Latest response was I was going to get credit after Ballito branch sorted this out. NOTHING! This is the most pathetic service. I will as I said continue to reverse payment. Please don't *****. I requested my recharge history and that stopped any action from Ballito. 4 months and still no contract. If I receive it now, will need to check for *****. # pay back my money minus the monthly subscription for a top up. Have some pride MTN!
