INDIANA -- Perhaps all of these "companies" are really just branches of a central operation. Here's the story of my encounter with Wellness Watchers MD, and luckily for me, it had a happy ending: Here are the events and steps that I took to resolve this: I got an email informing me of my "1 month free trial", at a cost of $1.83USD, and the email detailed the information about the charge to my credit card. I then called my credit card company and luckily the $1.83 had not yet posted (thankfully).
I then called the 1-800-591-6383 provided for Wellness Watchers and was put on hold for about 4 mins. before a Customer representative came on the line. He asked for my last name and zip code and then informed me that my account had already been deactivated. I went to my email and sure enough, there was an email from them confirming my account had been deactivated.
