Its more complicated than that - Netflix pays CDNs, transits etc for
delivery of much of its content.

The original email as I understood was a user seeing packet loss between
their business Internet service with Verizon and either a server hosted
within Cogent or another Internet access service. ie an end user trying to
connect with another end user/host. As such I don't think its about
Netflix, but this end user who is paying two providers neither of which are
delivering.

I would complain to both. I'd also try moving - preferably at both sides.
