Debit order gone wrong

Due to previous experience (two months prior to this) where I pay my account via debit order they cut me off. Full of excuses and many calls later and I was really ****ed off finally got my DSTV put back on, 3 payments later. On the 1st of October my debt order didnt come off so I sent an email on the 3rd to the person that helped me with the previous problem . which they rep**** that it had come off. I said to them its not showing on my account. Today I get an sms that I have been disconnected. I sent an email sending them a copy of tneir email. They phoned me and of course not helpful at all. Now I dont have money to pay. They said they tried to take money off up until the 7th and insufficient funds but they are lying. Since when do they allow you anyway to have dstv up until the 13th if you havent paid. This is becoming a habit on their side but I must be made a fool of and yes I definitely wont be pleasant to such imcompetant people. I lead a stressful life as a policewoman and definitely dont need this on a monthly basis. I have been with MNET/Multichoice for a very very long time. Are they trying to get rid of customers or keep them. They are getting alot of compeition, can they afford to be so pathetic. Do I find other ways to watch my movies or will they actually make an attempt to actually keep me as a customer. I am a good payer why do I have to go through this. How do they treat their bad customers.
