I have a broken back plate to the nest protect and can’t find one anywhere. I contacted customer support at Google and they said because it was out of warranty they could not send me one. They confirmed they have them and have the ability to send them out but refuse to let me buy one because it was out of warranty. There instructed me to contact where I purchased it and see if they had one. I explained if you have one and are unwilling to sell me one why Best Buy have. Anyways called Best Buy they do not have them and said I should contacting the manufacturer for individual parts. So not sure what to do any help would be appreciated.
