Transfer of phone number

I have Comcast triple play for years, recently bought a new home, just a few miles away.  In the same town, same school, zip code as the old house.  The tech arrived at the new house and installed the triple play service, this was just a transfer of service.  Then the problm begin.

When he was done and test the phone I had a different number, he tried  for 2 hours to get my old number back, but couldn't.   Then gave me a number to call cause he was done it was up to me to get my old number back.  With the tech in the house we were hung up on twice..

I have then spoken to multiple comcast people in 2 days now. And have been told it cant be done..  due to a 911 system issue. Of the station the number comes

from.
