REFUND OF MONEY

My mother joined bid4gold last year in May 2014. Because she didn't have a bank account I said they can deduct the money from my bank account. They called me and I said its fine gave all my details and everything they said its only for 12 months. They started deducting money from my account 30 June 2014 and up until now they are still deducting the money with an amount of R299 from my account but know for the last few months they are not just deducting the R299 there is an additional R30 that they deduct as well from my account. The 12 month contract ended almost 5 months back but still they are deducting. I just want to know why they are still deducting as my mother did not upgrade or anything. I tried contacting them but no answer and there is no other contact details for them or email address so that I can personally send them an email. Please can anybody help me so that they can refund my money and stop deducting money from my account.
