I ordered a month worth of product from Medifast in late May 2015. On July 15th they charged my debit card for an additional month without authorization. They claim we signed up for auto renew each month and they shipped a box of product to the same address as the original shipment went to. What they didn't know is we sold the house and moved out 1 week after the original shipment arrived, so there is no way we would have signed up for auto renewal.
After some online investigation, it appears this is a common practice of this company, as there are many complaints very similar to mine in which they say you signed up for auto renew and just ship product then make you pay for return shipping. I am working with my bank to get over $400 dollars back but want it to be known they have some very shady business practices.
