Who called from 6502004727

This is another example of AT&T not doing their job.  Pull the plug for goodness  sake.  These dead beats should be shut down.
But, Noooo AT&T wants the money.

I just received  a call from this #, but since I didn't recognize it, I didn't answer it.   How can I block these types of calls?

Called 3 times today, on the 2nd call someone came on the line after a few seconds and asked for Mr./Mrs. horribly mispronounced my name. So I gave them a blast from the air horn I keep for just such a caller.

Called back and his phone not in service, be aware of this scammer !!!  I put number on my call screening list.

This number shows up on my caller ID but they don't leave a message.
