Who called from 2062741299

Got a call from this number

Called and went to voicemail. Left no message.

I am on the national do not call registry. I tried to call them back to alert them to never call me again and to check the national do not call list before loading their robo dialer. My call never went through.

I tried calling this number back and is busy.  I have blocked this number completely now. But I am sure they have others

Called my cell. MrNumber.com reports this as a telemarketer fishing for donations to some charity (but don't/won't give the charity name).
Now BLOCKED.
