Is it just me or is there a noticeable delay in getting points credited after stays?

In the past year I would say almost half of my stays don't get credited automatically although I book via my account on clubcarlson.com

I have dutifully filled in the claim for missing stays email but even this seems to be taking ages to get a response.

Am I just incredibly unlucky or is it a wider problem? I'm a few stays off Concierge so am keen to make sure they are counted before a longer stay in Russia later this year.
