My job requires me to work in peoples homes. since covid is bad where I live my company has limited the type of work that that I can do inside the customers home. Today a customer had issues with a piece of equipment I brought to them yesterday (I wasn't allowed to install it because of covid and as luck would have it I got assigned the job the today and i was the reason the customer felt like they were wronged ) so I showed back up to give them new equipment and activated it in their living room where I was allowed to work, verified it was working properly then handed them the equipment to install in their bedroom and of course the customer couldn't get it work. Things went south when I told them I couldnt go into their bedroom because of covid so we can credit their account for equipment that isn't working but there's nothing else I can do for them until we go back to BAU. The guy instantly starts yelling and asking for my supervisors number so I give him the desk number and start walking to the door as soon as I opened the door he runs up shoulder checks me, knocks me away from the door, then slammed the door shut and proceeded to block the only exit. At this point I backed off in to the kitchen while he's yelling that I'm not going to leave until his problem is fixed. I tell him to let me leave now or I'll call the cops, he starts yelling more and throwing his hands up and pacing back and forth toward me, luckily his wife started screaming to let me leave and after what seemed like 2 minutes of not being allowed to leave and his wife screaming he finally stepped away from the door and allowed me to leave. I keep a fixed blade on my belt and a pistol in my pocket and i think i could have been justified to have used them to force my way out but I choose to not let him know they were there or be aggressive. This was the first time I was trapped and couldn't escape a threat and started mentally preparing to engage if i had no other options. I think I did it right but would you have dawn your weapon and forced your way out or just play hostage like I did? What are your thoughts?

Edit: tried to make it more grammatically correct but im not that good or determined
