Why am I getting calls with my name and telephone number on my caller ID?
I can tell you that I have had similar instances of this occurring on both my cellular phone and home phone. There seems to be a "spoofing" scam where fraudsters are using your own number to call you and others.
The FTC has a a fantastic article about these type of calls and the actions that you can do to protect yourself (article found here: https://www.consumer.ftc.gov/blog/2015/07/getting-calls-your-own-number).
Per that article: "Bottom line? These calls from your own number are illegal. Don’t pick up — or press buttons to be taken off the call list or to talk to a live person. That just leads to more calls. It’s best to ignore them, and move on with your day."
Unfortunately Comcast cannot stop these actions from happening, but we do have some calling features that can help to combat these type of unwanted calls.

We also always recommend that you report these type of calls (every instance) to the FTC and/or FCC; their information can be found in the article listed above.
