Will someone with the Hilton Signature Visa by Citibank please call the company and ask them how they treat the merchant 4829 (C2it). Do they treat it as a purchase or cash advance. If you are using a MC the code is 6529. Citibank gives out lots of different cards that give different things. You can see this at their web-site. However I have not seen the Hilton card there - only at the Hilton web-site.
