Exterior Wall Coaxial Cabel outlet

How do you install a new coaxial cable outlet with Xfinity? My condo unit has no outlet and I have had 3 technicians come and say they are unable to install this and said the wrong visit type was listed on the ticket.

the last guy freaked out and said “the Xfinity dispatchers are retarded” and left without helping.

Is this not something Xfinity does? How do I install a new cable service?
