Support have been really good for me, with a quick turn around on responses. I too have supplied them with video evidence and logs.
Though their last post has left the issue a little..... open ended. 😕
Based on what you have provided so far, I would like to ask that you allow us some additional time to look into further instructions for you. We will follow up with you as soon as possible.
Hopefully their investigation comes back with something concrete.
Especially as I just cancelled an accepted return request with Currys for the whole kit. I reasoned that a small scratch on the lens isn't really all that important, and it'll be many years before another opportunity arises to get into VR for as little as I paid.
My guess is that're working out whether it's a sensor mis-calibration that can be resolved through software/firmware, or if they need to issue new controllers.
