problems after exchanging dualview decoder

after i swopped my decoder my account was deactivated twice, problems with debit order,package upgraded without my consent and this was verified by the call centre going back and listening to all the calls. august billing was not done. my normal bill is R530 in september they took R1636. spent in the last month over 4 hours on the phone with the call centres. promised by different people that i will get a call back with but still nothing. utterly digusted with service. posted a complaint on dstv page on facebook but no response
