On april 16, 2010 my spouse and i attended a seminar regarding time share w/ geo. They made several promises. One was a $50.00 gift card. I was told by them not to use the gift card at a restaurant because they would charge 18% gratuity, and to use it for gas. So the next day on our way home to california we tried to use the visa gift card for gas. It came back invalid. When i called the 800 number on the back it said zero balance. I have written documentation showing this is part of the promise for listening to 3 hours of geo preassuring me and my spouse. I told geo to let me take the information home to read it because it. They did not want me to take it home and read. When i kept telling them i didnt want it, one guy started yelling to get us out. Very unprofessional and unnecessary.
