I have had this happen once, I posted about it on here and was then contacted through PM by someone from Hilton. We communicated about it through email and they wanted to confirm some information (like my social security number, a few credit cards numbers, my mother's maiden name) which I gave to them since they said they were from the Diamond Desk.

Ever since then I seem to be racking up the HH points from all sorts of exotic locations I have never been to...


No seriously, the first part is true. I confirmed my HH# and they confirmed that the front desk agent at the property keyed the incorrect HH#. They apologized about it but I am pretty sure that they left the points in my account.

I think other FTers have also had stays post that they did not make... I don't know how you would search for it but it is in one of these threads.

I think in most cases when they call to make sure everything is on the up and up, the points (or possibly the stay credit) are left in the account.

I would call just to rule out identity theft. If they let you keep the points, yay. If not, oh well... they weren't really yours to begin with.
