I stupidly/greedily registered some IHG Rewards codes on my account about a week ago...before reading about accounts getting suspended.

Some accepted some didn't, on my Offers page I have 5 that were registered with an expiry of 31 March 2015

If I don't use my account before then will these just expire or delete themselves? Or is there a way to get them removed?

If I get my account deleted, so be it, I shouldn't have done it, what I am concerned is that I use points for a booking and they cancel the booking and I have no room when I arrive.

Any advice on the best way forward would be much appreciated.
