worst service ever

after contacting the call centre on numerous occasions trying to change payment details I was advised by a client care advisor at multichoice that my account was in good standing and that they had debited and received the full amount, I then went on to let her know that I would rather however cancel the debit order and pay cash every month as they seem to be getting the debit dates wrong, she insisted that I should just leave the debit....I have been out of the country for a month only to return and find out that my account has now been suspended and I am owing R 2055.00 I have been trying to get through to the call centre all morning to no avail, pathetic service if you ask me there should really be another service provider to provide the dstv service.
