Review on Ventline V2049 03 Colonial Plastic Plumbing by Aaron Kindler

I am ordering 5 Ventline V2049-03 Colonial White 1-1/2" Plastic Fans. I have ordered five (5) of the items listed above and have been billed for five (5). , but I only received one (1).So do I get an overpayment credit or should I expect to receive it soon?I have read the packing slip but I also have a copy of the original order and it says five.I am confused because I check the Revain website to see where I am or who I'm reporting this to. Either way I'll deal with it. But this is a great product.
