Question for you: why post here, a community that is largely a help forum and refuse to answer questions from people trying to help? There’s been a few here trying.
Follow up: how can you say they are refusing to replace your deck while also saying you’re still working with them? Which is it?
From the outside looking in it’s clear something isn’t working as expected which happens with tech sometimes. Acting like the only possible option is a device replacement while not answering questions seeking to help really feels like there’s missing info here.
Edit: just looked at you last link and it appears your dock is working now?
