Timeshare Advocacy International, LLC Took my $3,495 & didn't help cancel my timeshare, will not return my calls, will not return my money Mount Juliet Tennessee

I hire this company on 08-21-14, paid $3,495.00 for them to help me cancel my timeshare with another company. they advertise guaranteed or get our money back, they also advertise that they will help you all the way through by calling the customer on a weekly bases. they have not done neither thing. I had to do everything myself, call my timeshare company, send my owe letters. and as of today 03-31-15, the timeshare is still not cancel, when we called this company they just give us the run around. They never return my calls and have not done anything else to cancel my timeshare. I called them on 02-04-15 & email them requesting my money back and they return my call saying that they don't refund payment. I have all my notes on who I spoke with. and when I ask why haven't they call us they claim no one answers my cell. but on my phone logs it shows no such calls from them no emails, no messages. I paid $3,495up front and now I just want my money back. they promise cancellation in less than 6 months but this is taken over 7 months with no results.
