I rent my home and there's no coaxial plug to plug my box into for TV, etc...

Hi there xFi!!! We received our xFi box this eve, but there's no coaxial plug to plug into wall for access.  It says I need to have someone come out.  What will happen next??? I don't own the property, I rent, and we have no phone jack even.  The building was built in 1915.  K didn't ask if I had a coaxial plug in the wall to plug into.  Will I have to have it put in??  And how much would it cost?? It's Not even my building, now what???
