I wanted the free trial, I have been charged 2 mos 89.00 for this product I do not want. I want it stopped now

I was worried when my free trail offer arrived with absolutely no documentation and no phone number to contact company to return the product if I did not wish to continue beyond the trail period. I still wanted to try the diet products, so began taking the pills. Imagine my surprise when I was unable to pay for my groceries a few days later because of insufficient funds. Upon checking my bank statement, I discovered that my debit card number was being used in Las Vegas, Nevada at a Target store, Lowes, Food4Less, and Albertson's for over $900; all charges were made on the same day. In addition, there were charges totaling over $250 for the diet product and other small charges at various places. My entire account was drained.
