New construction home, Landlines in our neighborhood but told they don’t service our addressorhood

We purchased a new construction home in a neighborhood with homes that have land lines and cable service (no internet).  I have spoken to customer service and sales and was told AT&T doesn’t service our area.  We have a green box on the corner of our lot marked Ameritech which is now AT&T.  They said they would send an engineer out to confirm and would call me back.  Never called back.  I’ve now called customer service and sales and have spent well over 5 hours over the last several days.  Nobody could see the request until I spoke with a final customer service rep that said the day after the engineering ticket was placed, it was reported back that our address was not serviceable.   Our neighbors all have service to their houses and I don’t understand why they say we are not in their service area.  Is there a way to get someone to come to my house to see their box right on my lot?  We need a landline for a medical device and emergencies.  They keep trying to sell me a “wireless” land line which is not going to suit the needs we have.  If anyone can help me find who I can call directly without going through the same run-around that customer service and sales is giving me, I would greatly appreciate it.
