Complaint Review: Grand Incentives

We were supposed to receive two "free" round trip airline tickets within the USA.  What we were not told is that there was $50 processing charge.  We paid it and were sent a form to choose 3 departure dates, at least 90 days in advance of our travel.  Each of the dates had to be 30 days apart. So that extends things out 6 months.  We filled them out, mailed them in, and after two months got a form saying that none of the three dates were available.  With a 90 day lead time, and 30 days apart, how could no flights be available?  On the internet, there were TONS of seats available, on various airlines, for each of the dates we picked.  Our options are 1-request three more travel dates, at least 90 days from now and 30 days apart or 2-get a resort certificate which, guess what, isn't free, and applies to certain resorts of their choice.  My guess is that the resorts won't be available on the dates that we request.  I'm going to try to get a refund, but I am not confident that I will.  For anyone out there, please be very cautious when dealing with this company.  How many ways can you spell RIPOFF?
