Vodacom *******

Yet again Vodacom is trying to ***** my money. I tried getting a response and nothing worked, then i used Hello Peter and got a response. They promised to cancel and eventually they did(apparently) but still tried do debit me again. I paid an early settlement and they still debited me which i left but now they trying again! Which lawyer can help me? I'm tired of Vodacom's disgusting service thinking they can bully people. I purposely made sure their wasn't enough money in my account because I KNEW they would try debit again and again. Who is going to pay for the bounced debit? I have all the necessary proof to show how Vodacom are *******!
