Forced to fix their mistakes and loose money in the process

So vodacom decides to double debit my account after I've paid it.. I call support and I'm told they can't help me I need to go to the bank and have the debit reversed.. I'm livi because 1. I live on a game reserve nearest bank is two hours away and I can't just stroll to there and 2. I now have to go out of my way to fix an issue they caused. I'm on the line answering stupid questions for 20 minutes only to be told "best I can do is as you to go and dispute the debit with your bank" are they going to refund my bank charges? I think not.. I'm five to canceling the flippin contract as this point. Dismal service. Poor firm vodacom. Poor form
