Elite mobile taking R200 from my account

I bought a vodacom tab for R99 a month in Novemebr 2015. I then noticed Elite mobile taking approximately R200 from my account. This is without my consent. I remember getting a phone call from a company trying to sell me something for R49 a month. I declined their offer. Clearly they do not understand what no means. I am not interested in any other service for my tablet. I would like that money paid back to me as well as the stop order cancelled. I have already been to the bank, but because Elite mobile has failed to cancel the order. back to the bank I'll go.
