identify technician

A man came to my house today saying he worked for DirectTV and wanted to know if my signal was ok because several of my neighbors have been complaining. This man had no lanyard, no uniform, and drove a dark brown sedan with tinted black windows. I ignored his knock at the door bc I figured it was another package delivery guy but my daughter observed him through our small window walking around our cars parked across the small street, talking on his phone and continuously looking back at our house, staring at it, staring at my husband’s truck and my daughter’s car, standing in between them and hanging around, looking back at our house while on the phone. We then figured this man was someone related to our HOA and was calling the police over our cars being parked wrong, or something. The man was short, dressed in street clothes (white, golf type hat, shorts, white shoes, white polo with some striped coloring), with a tattoo on his leg. Given that my male neighbor recently tried to attack me over parking, I told my daughter not to go outside, to wait and see if the police showed up and told us to move our cars and we’d worry about it then. I then went upstairs to spy on the guy. Eventually, he left the area across the street where our cars are parked, after looking at the tires, the license plate, in the bed of the truck, and starting messing around in the passenger side of his dark brown sedan with tinted black windows. While I was observing him, I witnessed him take either his hand or a hand plus an object and shove it in the waistband area of his pants, after looking back and forth several times, up and down the street, to be sure no one was watching. He also, again, had looked back up toward the windows of my house. I swore his actions bore resemblance to someone stuffing a gun in their waistband, maybe he was just adjusting his junk, idk, but it made my blood run cold as I watched him doing that. He then spied my dad coming out from doing yard work and made a beeline for him, identifying himself as a DirectTV man and asking if our signal was ok as he had spied the satellite on our roof and several neighbors had complained about their service. My dad hollered in the door to my daughter, who then hollered to me, asking if our signal was ok. I said yes and I heard the man cheerfully say, “alright then, have a nice day,” or whatever. His partner apparently joined him, they got in the sedan with black windows and drove away. I think I’ve seen that car parked near my house before. We live on a quiet street with a lot of new homes. My question or comment is wondering if this sounds like normal protocol or if I should report it to the police? I have read of scams with this type of thing before. The man did not wear clothing or drive a vehicle that indicated the term DirectTV anywhere or in any way. In the case that he wasn’t shoving a gun into his waistband, even if this man was just scratching his junk, how unprofessional!! DirectTV needs to make sure it’s servicemen act more legitimate than this man did. And if he wasn’t working for them, I need to know so I can call the police!
