Castle Law Group Failure to keep the contract we signed Nashville TN Tennessee

In March 2016 I entrusted my payment to Castle aw Group to get me out of the timeshare I had. All indication was that this would take about 6 months and that I would be free of any further connection to the timeshare. It is now April 2018 and nothing has been done. All I have received is broken promises and the standard answer to be patience. Castle was very quick to gather their fees but since that date, no communications have been exchanged except we are working on it. I have had very little communications with them and I believe that is a sham. All I am looking for is the return of my fee paid or the completion of the work that Castle Law said they would do
