spotty to No Cell Service near Sanford, FL Airport

We recently moved to a new housing community next to the Sanford Airport. The cell phone service is spotty at best / next to nothing in the area. 5g shows up for a brief second then disappears. The main road to the area is VERY busy, and i'm surprised that this hasn't been fixed. On the coverage maps it shows we have full service in this area.. in which we do not. The horrible thing is the houses that are being built are mostly healthcare workers who use the Verizon network. We had a meeting last night and confirmed that Att was superior in our area but we have never had issues before with Verizon. How do we get a engineer to survey our area again to fix the dead spots/ no coverage areas?
