Order arrived less one part

[CC&M]

I received my order yesterday and the parts look very good, with only one problem. I ordered 10 pieces, and only recieved nine. The package was not damaged in any way, and still has the same weight as shipped. You must have one more of these parts at your facility. The order # is 172097

I've already done this and got the automated email, which still doesn't solve the problem that I was shipped nine parts instead of ten. Can we please work towards a solution instead of running me in circles?
