account payment and reconnection

very unhappy on the 12th march '16 phoned cutomer care and the self help serv for amount payable to get pvr reconnected again the lady say R389 i paid R400 phone them again asked to be reconnected which was done the next day the one walke was still disconect phone them again and had to pay another R49 but i paid R100 now allready paid R500. on the 16th march pvr was disconect again when i phone they told me i did only pay arrears amount and not subscribtion. now i need to pay R918 to be conect to end april. i just feel that if they tell you amount payable that this is the amount to be paid and not another 2 days later. now my tv is disconected again and they are soooo sorry for me being misinformed. this is giving them an bad name as i will tell every one about this and they can even have a listen to the recording of my phone call on the 12th march. i cant be disconnected if it is not my fault? i feel the lady in customer care and the accounts dept should held liable for my inconvenience. as i did not mislead dstv like they did to me. and all i want is to watch tv for a chance. where should i get the extra money now for their mistake?
