Smart Travel & Incentives Free Travel & Hotel promised but not provided Lake Mary Florida

My husband and I attended a 90 minute presentation for a travel company.  At the end of the presentation we were given a sheet to fill out before 21 days and send it to a travel company in Lake Florida named Smart Travel & Incentives.  We did everything they asked and later realized in small print that they stated it needed to be certified mail.  Why????  

This evening I received a letter and the voucher that we filled out.  All across the voucher it had a void stamp and they stated that they regret they cannot help us any further.  They didn't even do anything except refuse to take our voucher because it was not certified mail.  What a joke.  

After receiving this letter, I was furious and looked up on the internet and found all of these complaints about the company. They either have taken hard earned money from people, refused to give out airline tickets because of one reason or another and have scamed a lot of individuals.  Our judicial system needs to get ahold of them and straighten them out.  They should not be in business at all.  They are getting paid by the companies that put on the presentations and then they are not holding up their part of the bargain.  

You can be sure that I will let everyone know not to get sucked into anything like this in the future.
