Incorrect billing and no one gets back to you

This is a follow-up to a previous complaint I wrote on hellopeter about Multichoice. On the 4th of August I phoned to downgrade my services. The call centre agent confirmed that she had scheduled for this to take place. It then doesn't happen and around the 20th of August all my services get suspended because I haven't paid for the premium subscription that I asked to cancel. I have tried phoning the call centre about this issue. I have spoken to agents who promised to find out and get back to me. I have scheduled calls with the person handling my account. And no one gets back to me or sorts it out. It still says I owe Multichoice more than R1000 when I owe them nothing???!!!!!Then after my previous hellopeter complaint sent a week ago, I get the Multichoice standard reply stating that they are very busy but that someone will get back to me within 24 business hours. That never happens. Terrible Multichoice. Your arrogance in how you treat your clients will result in your downfall.
