Newest update our device, not working

Since the last update on September 30, I haven’t had any audio. I tried everything I could do and nothing worked. Just got off the phone with customer service. Followed the steps They told me to do the whole time while they were on the phone. Now my device will not work. no video or audio. My ring doorbell is only a couple of years old and never had a problem with it until this last update and after speaking with YOUR customer service rep! It won’t do anything and completely useless because of what YOUR customer service rep told me to do! I the ring doorbell a lot because I am a cancer patient and have issues getting around. I am very angry and want this resolved ASAP
