Need bill for my Comcast service, I pay services via HOA

I receive Comcast service from my Home Owners Association. So I pay a single fee that covers Comcast + many other services.

For tax and employment purposes, now I need a letter from Comcast stating what's the value of just their service.

My Comcast bill shows all 0 because I'm billed from my HOA.

Anybody at Comcast can help?

Thanks
