Dental pro global Dentalproathome.com Shock and disbelief Internet

 I responded to a pop up advert on the Internet for a free trial of tooth whitening applicator.24/6/2013 The following day I received a telephone call offering me vouches to save me money off products if I paid a fee of £2 as I knew it was connected to the offer for the dental product I stupidly agreed as it was only £2 . I do not do Internet banking , but as it happened I received a statement from my bank three days later and was shocked to discover the £2 charge was after reading the email address was going to take a sum of almost £20 per. Month from my account for this service, I must add that this was not mentioned in the telephone call. A telephone call to the company resulted in the monthly charges being cancelled I was asked if I had received the dental product ,I replied no and that I did not wish to receive it after all .I was given a reference no. And assumed this was final. The dental product arrived about a week later there was no invoice in fact there was nothing other than the product in the box. Today18/07/2013 I have received my monthly bank statement and there is a charge of £64.93 to this dental company I then called the voucher company and they have told me they are nothing to do with the dental company ,they did not tell me this when I contacted them . I am now in a very distressed state and do not know how to cope with this situation . The A Money
