Debit order,extra charge , disconnection

This is the 6th month this issue not resolved. I had been in contact with dstv several times to link my debit order on my account and every month i get disconnect until I go to pay in cash. Today same thing happened I switch on decoder & it disconnected.i went to pay in the morning, I come home this evening it still disconnected. So I had to buy airtime & I waited 6 min for call to be picked up & I explain the situation to this guy & he tells me that I hv been charged extra for late payment but I arrange for DO to go off on 29 monthly. They say they didn't get confirmation from my bank. But why they didn't contact me so that I can check with my bank what's matters. Im really furious & disappointed at multi choice for such pathetic service. I even regret why I opened this account if I have to suffer every month. Annoying part is to hold on phone long and still not get assistance. Worse they refuse to connect me & last time when I address this issue with them they said it will be sorted.The worse part is not getting a feedback from multi choice dstv team leader or manager. Maybe I should consider closing this account. Sharon ***.
