How does not responding to a phone call have anything to do with Covid. In fact quite the opposite. If he isn't taking customers, ,then a courtesy reply or text letting someone know (someone who took the time to reach out to him) - would be a good gesture. I'm sure anyone would respect that.
Also if you are not taking appts due to Covid, then take down your ad.
Just being honest here guys
Btw re-read last few threads... the red flag wasn't for not calling. But rather for multiple profiles, phone numbers no price, no reviews etc etc
