Frozen account still being charged

I have given up on vodacom. I will be moving once everything has been sorted. My number now has been listed as non existent. I have had a torrid time with this service provider honestly.

Got a call from them yesterday and they couldn't find my account - Is that even possible, how?

I bounce off some emails with Cassandra and now she tells me to call the Accounts department. Yes, you read right, I must call them, when they made no effort to communicate with me. It's truly shocking. Absolutely shocking.

Extremely unhappy.
