I called HHonors Diamond Desk a second time to try a different agent's response. She said that for some reason the reservation contained my email and home phone number on this record. She also said that it was done by the Hilton Molino Stuckey. She put us on a three way call directly with the hotel and the the HMS rep said he would ask his IT department to investigate what happened.
As said before, the last time I stayed at this hotel was 2013. I have no idea why my data would be integrated into someone else's reservation.
The Marriott situation, I have never stayed at that hotel.
