This wasn't from Comcast, although she asked about my recent service tech visit. If Comcast wanted to know how the tech did, they would call, not some other company. Beware!

This was a cable and tel contractor for Comcast.  Calling to follow up on customer satisfaction.  I did not answer and they left a respectful voicemail.  Not a dangerous number.

Comcast uses subcontractors to do work and they follow up so you don't complain to Comcast.  This is an OK call.

got a call from this number, follwup call on recent cable problem. They did leave a message to call if any problems, it was a real person.
