Cancellation of Clientele policy

Hi, a year back I was stopped and pressurized by Clientele sales people, cannot really remember their names but, I was told to join the Clientele Legal Plan, the guy said that he would only be taking my details to firstly approve if I qualify for it, thereafter I would get a call and they would ask me if I am interested, up to this day I still have not received a call, yet money has constantly been taken from my account, recently I received a message that said an amount of R270.50 will be taken from my account within 10 days of the 23rd, and earlier this week, I received a phone call from a sales consultant and when I had asked him to cancel my plan, he ignored me and continued to try and tell me about another plan after I had told him that I do not have the money for neither, please help me cancel this policy since I do not have the funds to pay for it.
