For me it has been 5 months since I moved from Gold to Plat and nothing happened to my HHonors status. I called Velocity, they said call Hilton, as it was not Velocity's responsibility to change it after you had initially signed up. I called Hilton, they gave me an email address to send details to. Who then responded telling me to call Velocity. So I sent a PM on Friday but have not had a reply. Hopefully it works out. I have put effort into staying at Hilton's and I would like to experience it as a Diamond at least once!
