Tap Installation

We recently signed up for service. a troublesome pole was repaired and now the fiber cables have been lashed and the pole is stable for Xfinity to come out and install a tap, unfortunately of the 2 time we've had a technician out to the home we're try to get set up, they have been unable to install our router and modem as a tap has not been installed on the pole, and the closest is rather. we have been waiting WEEKs to start service with no word of when our new tap is to be installed. who do i get in contact with?
