I paid $699 to "list" my timeshare with Blue Solutions after receiving numerous calls from them about how we had to post for the coming weekend's gathering of corporate rental groups. Whenever I called or emailed them I received a quick response. However, once they received my Am Exp number to charge it, I NEVER received another call back from them and they did not respond to emails, etc. I have refused to pay the $699 and Am Exp has returned the disputed item to me. On another website, one of the responders made a great point "why do you have to pay in advance"? If they rent it, you pay them, it not, nothing lost. The only reason I went through with this transaction was that I knew I had 30 days to decide, and if it didn't work out, that I could dispute the charge.
