866-940-6057

got a call from 1-866-940-6057. please let us know who/what number belongs to.

866-940-6057 is COMCAST Troubleshooting Dept. [Comcast provides Cable, Internet, and Phone services.]  They're instructed to not leave messages but rather to keep calling back until a person is reached.

Not true, I don't have comcast, and they call incessantly

It is comcast and no they won't leave  voicemail.

probably comcast
I reported a problem yesterday to their troubl eshooting. Service came back just before this number called, but no voicemail left.

no voicemail left. called my cellphone and i didnt provide such a number to any telemarketers.

I can confirm that it is Comcast troubleshooting - just spoke with them to confirm a service order that I placed.

yes its Comcast, same deal, no message left, I called back and a Comcast operator answered, wanting to make sure my internet was working okay as I had recently had issues

Yes it is Comcast and they did leave me a message.  I called them yesterday becuase I am having problems with my service and I set up an appointment for tomorrow.  They were calling to confirm my appointment.

Comcast

I have received nearly 10 repeated phone calls from this number today. I sent most to vm, which they leave none. I answered one time and no one was there. SO ANNOYING!! We're currently having problems with our Comcast and have an appointment scheduled tomorrow, so based on the other responses, I'm guessing it's them.
