Yes they are scammers and yes I got  taken! Sent them $788 in Feb 2012 to sell my timeshare. The contract was for one year with  a full refund if they didn't sell it. In October of 2012 I was notified by another scammer that they were closed down for 'fraudulent business practices' and they offered to get my money back. Didn't fall for that one.

Today, 6/10/14 I got a call from (321) 250-6315 stating they were Sharp Innovations and had never gone out of business, just closed the GA office. He said my account has been active all this time. I said I wanted my refund and he told me there is an 800# on my contract to call for customer service. He offered to transfer my call and we were (amazingly!) disconnected. I did a reverse search on the phone number and found it is a very new number in Kissimmee, FL. One listing from 4 days ago said the number was currently available, so whoever this is has only been operating a short time.
