MTN worst service ever

MTN does not care about their customers. I had app**** for an add on to my existing contracts with them. Every thing was approved then I was told no stock. Eventually I got my laptop. Then my account got soft locked. I pay via debt order no debt order was missed. Now for the last 3 weeks I need to hear that my top up contracts is soft locked because I am over my credit limit. How can that be its top up?????? Then they say its because of the new contract credits needs to be passed. Its been 3 weeks and no luck. Cant use my phone lost a lot of data that expired because I cant use any of it. I am over it worst mistake ever going to MTN even worse than Telkom... worst is I have 5 line with then and this is how I get treated.
