Faulty Hub

Got a hub when they were first released.This one lasted 2 months before a grinding noise started.Sent a video in of the noise and was dealt with quickly and a replacement was sent to me 3 weeks ago.Unfortunately this new one is not showing any cadence as reported in another post,but despite email after email of try this and that and the live chat and the promise to send it higher up to get things sorted I am getting a absolutely nothing back.I am or was following training plans but that has come to a standstill.Any ideas of how to get things moving?

Hi @Colin_Houlden

Shuji at Zwift HQ here. I see your email conversation with my colleagues - I’ve asked them to continue toward a resolution offline, as we don’t handle replacement questions on the forums.
