Debit order woes

I took out the DPP subscription towards the end of January. Delivery and installation was done and R140 was deducted via Debit order. OK, so February rolls around - no deduction done. I phone the call centre to query this, and was told that \someone\" had changed my payment method to cash/ EFT. Now I know this was DSTV themselves as a few people I know got SMS messages informing them to pay their accts, as they were also suddenly changed to cash payments. After a bit of a fight was promised that this would be fixed. March rolls around - still nothing! I phone back and make a scene on the 1st of April, and also discover that they did not even have my e-mail address correct (aarrghh!). Now Godfrey promises me that they will do an ad-hoc Debit order for the outstanding amounts - still nothing! DSTV get your act together! And do not dare complain that I am not paying you, this is your stuff up!"
