Returning numbers ported to another vendor in error
Recently I was requested to port three numbers, one from each of three related sites, from Comcast in to Mitel. Two numbers successfully ported (took about 2 weeks), before it was discovered that those lines were dedicated analog fax lines that should not have been ported. The third port was caught and cancelled in time.
Where can I go to start porting these back into Comcast and returning them to the clients?
