Double debit

evening, mid month last month I took up a membership with you guys and when I did there was a campaign running "first premium back in full". The sales person told me bout the campaign and I was very keen and I joined. My 1st debit order was on the 20th May(same month) for R349 as per agreement and the debit went through. On the 31 May I then received an SMS saying there was going to be another debit order on the 1 June(11 days later). I then texted the sales person informing him about the SMS , He assured me that there was no debit order that was going to go off , I then asked him bout the refund which was still not done ; He promised to call me on the very same day of which he still hasn't. I do not have an agreement with virgin active to debit my account on the 1st. Before signing up I was treated like a queen and literally all my question were answerd within seconds and even got a sales person coming to my place to help me sign up and now that there are problems and I need answers the sales person is no where to found to answer my questions and worse now my account is being debited without my constant! Call somebody call me to resolve this matter **********
