I signed to join the 3 reward programs (Marriott, SPG, Carolton). I assumed that meant they 3 would be were joined together. So i have been doing business with SPG hotels these last 2 years assuming that the accounts were truly joined. I go to sign up for "infinite points" at Marriott which required me to sign in to my account there. That is when I discovered i had lost over 11,000 points. I started searching through the documents and find out that the 3 are joined but points to each are not joined. When I signed up, there was nothing saying that the points for the accounts would still remain separate. You had to go further into another page to see all that. I called and talked to a representative and got no where. Very disappointed in Marriott because they were not more up front on this issue. Come to find out i could even of just transferred those points to SPG. Very unhappy customer.
