I keep getting unwanted wanted calls from this person.

Received a call from this number. They asked if I was interested in further education. I said no and she hung up immediately.

I have not idea whose calling from this number...

I have received various "Unsolicited" calls from this telephone number.  Need to stop them.

Received a call from this number ot my private cell phone. Called back from a blocked phone. A lady answered thanking me for returning her call, then she went on telling me that I had inquired about furthering my education and mentioned some college name "garble speech when mentioned the name" (which by the way is not true). I said that she was wrong and then she hung up.
