Vodacom refuses to accept payment but still applies penalty fees.

Vodacom failed to debit my account last month. When I called to find out why I was told my payment method has been changed to cash. And when I ask when and by who, no answer could be given to me. I then arranged for the debit order to be rerun on the next business day, and guess what it did not run. Now I'm getting penalized for Vodacom's *****-ups! I tried calling again, but I got a message that I can pay via Internet banking. but again apparently the ref \ account number is incorrect. I tried calling again After being on hold for a lengthy period of time I got put through to an agent, then the agent just proceeds to hang up on me. Again I tried to call again, again being on hold for an extended period of time the agent hangs up on me. There is no way for me to pay my account and Vodacom refuses to debit my account as they have done for the past 15 years! I'm at the end of my rope, and Vodacom blames me!
