Refuse to cancel debit order and contract

Amazing vouchers phoned me and at first I fell for this deal but then I went on the internet and read more about them. This poeple is bad. I phoned on Monday ( 16 Feb 2015 ) to cancel this deal with them. This Fronia Williams phoned me today and told me theat I have to pay for 4 monts then after that the debit order will stop. So I asked her to send me the proof of this company policy rule of them so she did not. I went on the amazing voucher cancellations website and OMW all the clients who tried to cancelled got this issues with this company. Please Hallo Peter helpme as well as this other people. This is so wrong to do this to people.
