I don't really see anything in the OP's post that I would personally call a 'poor customer service', but it depends on one's expectations, I guess.

As for the bottles of toiletries, if they were empty and not replaced, I'd have called the housekeeping for a replacement. It wouldn't have pleased me to have to do that, but omissions happen, and being a Crowne Plaza and not a luxury hotel, it wouldn't have bothered me much.
