Received this call & applied my simple equation:
Unknown caller "+" no msg left "=" SCAM
If u respond to these "phishing" calls u'll be "hooked" for more calls attempting to drain your bank accts & likely funding terrorism!!!

Called me, no message no joy!

These people called back to back and left no message. Probably some type of scam

I answered this, thinking it was someone I knew. Nope. A recording telling me "my credit card" (but not saying which one) had been used and now I owed a lot of money. But they (didn't identify their company name) would help me "get a great rate" on a card. Totally scammy.
