I too have noticed errors lately. Making me wonder now just how much I've missed in the past . A few months ago I contacted IHG and they took care of it. Last week when I contacted IHG they blew me off as well--told me only Chase can fix. So I did the same as thealphalion, sent a secure message to Chase through the online credit card site. They respond very quickly, as in an hour or so. Except it took me 3 times of replying to their messages to get them to understand/accept that Venetian/Palazzo is an IHG property. Rep said the prepaid stays plus spend was "coded wrong".
