Poor services from Vodacom

I would not refer anybody to use Vodacom services. I have cancelled a product from them because no service was deliver in March this year from August they are deducting from my account with out my consent. Whent to the Vodacom store they just said its not there problem cant help me. Called Vodacom customer services emailed them and all they can say its not them deducting even though im sending my proof of invoice and statment that Vodacom is Smsing me and my bank statement with proof of payment to Vodacom. Customer services keeps on tellng me we wil phone you back Im still waiting for all the Vodacom workers to phone me back from march it doesnt even help that they give you a SR number because they keep on steeling your money.
