Hi- I signed up for a World of Hyatt Account a few days ago, solely to buy points with the current special. No matter what card I use on the Hyatt website, I get an error message that says "There was a problem with your credit card information. Please try again or try a different card." I have verified there is no issue with the cards and can use them online with other retailers. I have cleared the cache, used different browsers, tried different variations of my mailing address in case the abbreviations don't match- nothing works. When I call Hyatt they say they have never heard of this issue and I should try a different card. Hilton users complianed of similar messaging and point.com was the root cause, but they were able to call Hilton and buy points. Hyatt said there is no other way to buy the points. Has anyone been able to resolve this issue?
