There's definitely something a bit amiss with Creation's handling of the IHG cards. I planned to get my windows and doors replaced - a process which was delayed by a couple of months due to a glass shortage - and thought I'd pay on the IHG card (as they didn't accept Amex). To that end, I needed a higher credit limit on the card to pay the whole thing. I applied a couple of weeks back and they said they'd give a reply within 5 working days... but nothing came of it. If they can't even reply to a straightforward credit limit request it makes you wonder if they're a bit short-staffed, or whether they might be looking at pulling out of the card market entirely!
(In the end I put the rest of the balance on a Tesco card, not ideal but at least there are a few points from it coming my way).
