Recording claiming to be able to get my business listed at the top of Google search engine results.

Called two times back to back with no message. Blocked caller

Called 2 times back to back and did not leave a voicemail either time. I called it back and all it was was an automated message saying " hello, if you would like to be put on a do not call list for this number, press 1 now."  I did not press 1 and just hung up.

Just called me. Caller ID says Freda Mah. Didn't leave message. Blocked.

Received a SCAM call from "PG&E" simultanieously with this call.  I suspect they are trying to call to make your line busy and then following up with another call to get to your call forwarding number.  Called number back and got message that "this number has not been assigned".
