DSTV bad customer service.

I have had the most horrified experience with DSTV. I am currently on the compact package and I have PVR. My installment is R475 on the 20th of every month I pay R500 which means my account is in a credit now. On the 24th of September they suspended my DSTV account saying that they have not received payment. I sent proof of payment to them which they received and reconnected. Today on the 26th September they disconnected me again for the same reason and had to call me back to locate proof of payment which was supposed to be attached to my file. I have spent over R200 worth of airtime holding on and speaking to call centre agents who helped me temporary and some could not assist. Now its still showing I owe a balance of R446 and they have my proof of payment but finance can only clear this. The call centre agent agreed that I have been unfairly disconnected and that dstv has a glitch with their systems which causes disconnection. For such a big company this is really not acceptable. I asked to speak to a manager which did not get back to me as well.
