Exotic Journeys International Did not return the money I paid for the trip Chicago Illinois

I booked a trip with Exotic Journeys.  In their terms and conditions it is stated that I would receive all but my depost back from them if I cancelled at least 64 days prior.  I Emailed, phoned, and FedExed my cancellation.  Their response was that the entire amount I paid was non refundable.  This trip was even cancelled by them! They refuse to send me back the money and have now threatened me with a lawsuit if I post the true facts of my dealings with them!  I would avoid booking anything with this company.
