Video Doorbell Pro cracked button issue - replacement promised BUT nothing! Ring makes junk and is best avoided

Usual problem - Ring Video Doorbell Pro bought a couple of years back but the button's cracked already. Online chats with Ring produced two promises to send a replacement and initially I was impressed.That was in early September, but since then nothing at all. No replacement, and although someone calling herself Sarah promised to sort it out and emailed regularly for a few days, she's now refusing to reply and there's obviously not going to be a replacement for this expensive piece of junk.Result? The Ring alarm system I was planning to buy isn't going to happen, and I'll buy nothing further from Ring.I'd strongly advise anyone to avoid Ring like the plague - it's not a company you want to do business with.
