My first stay for a while... and my points didn't post. A 2 night pre-paid stay at the Cardiff Marriott. My question... I filled out the missing stay form, but didn't receive any acknowledgement that my request had been received. Is this normal?

I only filled the form yesterday, so I'm not expecting the points immediately. But I'd have expected at least a "Thanks, we've received you claim, your points will post in the next 10 days" type email.
