new condo needs cable

We've been trying unsuccessfully for a week to have Xfinity move the cable/internet into our apartment in Chicago from the common 'cable room' in the building, which has a contract with Xfinity. We waited for a technician yesterday through a 12-hour window. They never showed up. We followed up with X, were hung up on at least three times, and were finally assured that a technician would show up today. He did, but said he was not qualified to route the cable into the apartment. He told us he would have X contact us to arrange a  Multi Unit Dwelling technician. We heard nothing. So here we are. Needless to say, this is a corporate failure of communication, efficiency, intelligence and decency. Not to mention straightforward consumer rip-off. A simple plan would be appreciated.
