Comcast Issues from Hell

Lost service seven days ago.  Call Xfinity.  Tell me to take modem, and boxes into store to replace. They gave me a dvr that did not work and I gave them one that worked.  Took it back again and they gave me a reconditioned on that was operable.

The issue was the drop amp from Commstock.  I ordered from Amazon and replaced today. Had to configure everything.  Now, the same issue that many customers have: no dial tone on voice.  Call support > All they want to do is restart the modem.  This issue has been ongoing with Comcast for years. They want to send a technician out.  I connected the land phone right to the modem.  Not a wiring issue.  Step it up Comcast.
