Doorbell is trash and has been from the start and they wont help

1 My doorbell is notifying me if motion but no video is being recorded and 2 I still can't be heard when talking to someone through door bell and I hear lots of feedback I've had the 2nd issue since purchase and I've talked to them on the 2nd issue lots and it's clear they can't and don't care to fix that one do I hope they can fix the 1st issue.
