I am still waiting for my 10% rebate to be credited to my account for my reward night stay on May 16, 2014. I emailed IHG and the representative wrote the following:

"Please allow 4 to 6 weeks after Reward Night stay for rebated points to be deposited into your account, and 4 to 6 weeks after date of redemption for all other (non-Reward Night) redemption items"
