Do they even know what they are doing?

Last year November I called Multichoice and asked them to set up a Debit Order for me.<br> The debit order was set up and was supposed to go off on the 1st of December.<br> The DO never went off, so I paid them via EFT. Till end of January I paid them instead of DO.<br> End of January 2015 they double debited me. I called the DSTV contact center to find out what's going on.<br> The lady told me that there were TWO debit orders set up on my account, for different dates. She said that they were NOT going to refund the money I paid in, but that I had to go into the bank to reverse the debit orders.<br> That VERY SAME DAY, I got R655 transfered back into my account from Multichoice after the debit order failed anyway due to insufficient funds. I didn't have any money to pay them again as the money they paid back to me, went towards bank charges that have left my account in the minus.<br> On Saturday, 28 Feb, I paid them via EFT again as I wasn't sure whether the debit orders have been cancelled or not. Yesterday they double debited me AGAIN!<br> I feel that I shouldn't pay the money they sent back to me last month as they said they WEREN'T GOING TO!!!<br> Why must I keep calling them to fix THEIR ERRORSI
