Who called from 4242351318

Now that you've confirmed that your number is valid, you can expect to receive many, many more scam calls!

I didn't recognize number so I didn't answer the call. They left no message.

Answered. They hung up on me. I called them back. Machine asked if I wanted to be placed on a NO-CALL list. I pressed 1. What the hell are they up to?

Hung up. How and whom do I sue, if this leads to an avalanche of unwanted calls?

Asked about car I didn't have.  As soon as I said that they hung up.  SCAM.
