False information results in R1250 incorrect debit

I joined Virgin Active Bedfordview on 21 January 2015. My discovery Vitality was only being activated on 1 March but the sales person Izaan said that this wouldnt be a problem if I joined on that day since I would still be covered by the one month free special that they had running. She said that by the time my Vitality kicked in I would only need to pay the joining fee and thereafter my monthly debits would be at the Vitality rate. On 1 February my account was debited for R625. I sent an email to Virgin Active Bedfordview -no reply. I called Izaan and she said that the two weeks qualified as one month. This is NOT what she said in the sales room. She then said that if I payed the sign up fee on that day Discovery would also pay my R120 monthly fee and I would therefore be paying nothing to belong to the gym. I called my broker and they said this was not true. A manager from Bedford called and said he would look into it and let me know-he never got back to me. A few weeks ago I got a call from Michael at Virgin Active head office-he said he would look into it - no reply yet. On 1 March I was debited ANOTHER R625. Now they want to charge me and additional R1200 before they fix it!
