This number was identified by my phone provider as a "spam number"; therefore, would not allow it thru and our phone did not even ring. This is a relatively new service by Comcast and blocks all calls suspected of being spam. Has to be a scam or spam, since the same place called our number 4 times in a minute or so, despite being blocked. A very useful service by Comcast, because we have had many other calls that have not gone thru and bothered us since this service was started about a month or so ago.
