Go Glam debts bank account long after cancellation

Go Glam offered 5 beauty treatments per month at Milk and Honey Spa in Sea Point for R399 per month and R100 once off activation.<br> You can not get any appointments on weekends as they have obviously oversold the offer and I had to book 3 months in advance to get appointments during daytime hours. Weekends were not available.<br> When I took up the offer they telephonically assured me that I could cancel at any time and there would be no cancellation fee provided 1 months notice was given.<br> I gave 1 months written notice and yet they continue to debit my bank account. I put a stop on the first 2 debit orders after the cancellation of R399 but they are so sneaky that they change the reference number and even the amount that they debit. They have now debited my account twice for R199-50 which I have only just picked up as my sms notifications are for transactions of R200 and above.<br> Any suggestions on how I can put a stop to these ********** debit orders - can I lay a charge of theft as this money was ****** from my bank account.
