money taken by Hotelstay without customer consent

Received a call from an agent in Hotelstay Midrand selling a benefit card. She explained the benefits the card can give me and it sounded very good. I told Tumelo Deborah Makgumela, the sales agent that the package sounds very good but i need to check if i can afford it. she told me that there is a once off payment of R3 260 or one can pay it in 6 months. i said to her i will check how my finances are this month. She asked for my address to send the details for me to go through i gave her my details and ID number. She asked for my bank card number. i asked why she needs card number and she said it is to link the 2 cards together. I then realise that these people went to my account and took money. What is puzzling is that these people take money as a purchase without the concern of the client. As much as they sell a good package, their dealings are ********* because they trick clients of their monies. All i want is for Hotelstay to give me money back as i don't want anything to do with them. They are dishonest and unprofessional.
