Claimed to be from some marketing company.
Sounded like a fraud, told me that I had won a $100 gift card and that I needed to make a deposit of $5 before receiving my gift card.
I've dealt with tons of these before.
Understand that if you answer, it tells them it's an active number. Right these numbers down and if you don't answer they usually quit after 3 tries. Or, call your phone company or cell provider to see how to block the calls. Verizon has a way, my Comcast land line lets me go to their website and block the number. Eventually your number gets taken off the list. When you answer they keep you on the list.
