IHG Plat
I called up last night & they too said it was a mistake that I was sent a platinum card & letter.
Perhaps someone can get a nice pdf version of the letter hosted somewhere so people can send it to IHG?
I spoke to the rewards club & they eventually agreed they should honour the card & letter they sent. So they will put you back on plat if you were sent a letter/card.
Logged in this morning & back to Plat.
