call centre agents and supervisors

So my old decoder decided to die yesterday. i purchased a new one but had problems with the pairing of the extra veiw. so like any normal person i called the call centre. now my accounts suspended and R300 airtime and 15 phonecalls later my problem's not resolved and all i get is unhelpful call centre agents. my account is in credit with R400+ but my service is suspended. all i wanted to do was change the decoder and now i have endless problems. before my call to the centre everything was fine. i logged onto my selfservice online account anf guess what, no decoders are listed
