I had comcast come today too and had 2 calls from this number.

This # is an automated survey following a Comcast service call.
Yes the tech was great!
Yes Comcast has the absolutely worst call center in America.
Can't afford to add bodies during peak(always) demand.

comcast tech finished at my new apt one hour ago, received 2 second blank msg from this number also, cannot actually confirm source but makes sense given other experiences above.

thanks for the info. I have gotten 2 calls today, about an hour after the service tech left.

Thanks I just had the call and we had Comcast at the house this morning . . . that was great info!
