Useless service even from the Supervisor

we called 4 weeks ago for there special on there explorer deal for R149.00 p/m, for that amount of time there was still no response or help from DSTV regarding this we wasted a great amount of time and money to call there call center and we just get incompitant people every time they cant speak right and there knowledge is like in the 0%, we are furious regarding this matter, they have been just full of promises and keep saying they will call us back but we never receive a call, they do not care about there customers at all, they did not even deduct the bill for our premium service for last month and now they say we must go to our bank and sort that out, but weirdly enough there was more than enough money to deduct. we have even spoken to the supervisor on duty for more than an hour on our phone bill on the 05/12/2015 and he promised to send us the statement that same day and we still did not receive any thing. he would also have made a urgent deduction on that also the same day but nothing happened
