AT&T missing multiple appointments

Hello,

We have had multiple appointments scheduled and no call no show.  Original 5/18/23 (no call no show), Second 5/22/23, no call no show, Third 5/30/23, no call no show, Fourth 6/5/23, no call, no show.  Now I have an appointment for 6/7/23.  Have have zero confidence they will show. This is new fiber for a business move.  AT&T shows that the address is available for installation.  I had been communicating with two different reps via email asking about status.  Both have stopped communicating with me. Funny thing is AT&T is already in our building.  I have asked for the local contact, but the reps will not provide.  If they would call and give an update, that would help.  I have to call and ask.
