Who called from 7204646123

This number keeps calling our house phone. Never speaks when we do answer and now we are not answering and they
don't leave a message.
Not sure who they are, but this is getting to be ridiculous. starting at 8am today.

yea this nmbr calls, and it says nothing, when you call back no one answers, annoying

First national debt collection is how they answer the phone.

This number calls either right before or after 877-236-5791, which is Stellar Recovery on behalf of Comcast.  I have never had a Comcast account.  If you answer, no one says anything.
I think someone is calling from a private cell phone to see if you will answer, so they can call back on the "official" number.

They call all the time never say a word or answer call backs
