Nonexistent service when dealing with Multichoice.

Have had a Mutichoice DSTV subscription since its inception. Monthly debit orders are in place for convenience and continuation of service. Last Tuesday, I received a notification that my subscription had not been paid, despite the debit order in place. Sent proof of payment for verification, but still been told that I must pay an additional amount of R440.30 to activate the service until DSTV can verify 'my' proof of payment. To add insult to injury, Multichoice charge me a fee of R50.00 to reconnect. A week later, still no response!
