Slim Rx Medical Weight Loss

Bought a Groupon and went for weight loss. The first visit I ended up paying $450 for the required supplements and to continue the full program for 2 months. After the first month I was losing weight. Then they wanted to draw blood "as part of the program" to send off for testing to get a baseline. They asked for my insurance card and assured me that it was all covered by the program and anything the insurance didn't pay was covered. Imagine my surprise when I got a bill for $279. I took the bill to the office and was assured it was a mistake and they would take care of it! The next month I got an OVERDUE bill from the lab for the unpaid amount of $279. I have called the office several times, no one ever answers the phone or returns Voice Maill messages. I have sent emails... no reply. I no longer live in the area so I can't go to the office, so I'm just warning others to beware of ALL the hidden costs involved!
