Hi I was also conned by the Lean Body Burn suppliers. Not realising i would to pay a further £61+ for the trial. To cut it short with the assistance of my credit card co. MNBA who put me through on the phone to the suppliers and with the knowledge the call was being recorded by them. Shorely with todays technoligy the phones shouldn't be that bad.
Any way they sent me a cancellation e-mail and the site it is on is:

You require your customer number.
Fill out the boxes. If in the uk put x in state and zip code boxes. In the telephone box put their number or this will not work. The password they gave me was: online, lower case.
Hope this works for you.
