5 calls later and still no service

My single view decoder broke and I bought a new decoder. I have a primary hdpvr decoder and a single view. I phoned in to disconnect the old one and connect the new one.(was not done) The next day I received a bill stating I am in arrears. I phoned again and the lady said the previous lady did something wrong. She corrected it? And she did a journal to correct the bill?. When I got home that day my pvr and primary decoder was completely off. I phoned in again and a different lady said she would sort it out. Which was not done. I phoned my TV guy and R800 later all the settings was done but still no reception on the secondary decoder. I phoned in again spoke to Sipho. He said the system is slow and would phone me back to say if it has been activated and the bill clear. No phone call. I phoned in again spoke to Rodger, he said I must sent a sms with the error code and smart card number (10 digits).as the system is off. I did it twice and both times sms came back can't process the request. Please note that in my house there is no cellphone reception, so every time I have to run outside / on the roof to be able to speak to a person. Please help!!!
