Moving to a different apartment in the same physical address

I cannot get the Comcast employee I am dealing with to honor my request for a manager escalation, so I am turning to a user community.  I called last week to coordinate a simple move up one floor in my building, and was told all I had to do was sign the work order and a tech would come out this week to help.  I am now being told that I require a new install, new contract, new IPs, and that the work cannot be started until the 12th.  This does not work for me, and I do not understand why an existing business class customer would be treated this way.  I am ready to terminate my service completely, since I could get another ISP to do the same work without the run around.  Can anyone provide a point of contact for escalation within Comcast Business?

Many thanks,

Dan
