These guys tell you they are from a Payday Loan Company and ask for you. Somehow they know your name and sound like they are from another country. If you tell them not to call again they tell you they want to f_ _ _ _ you.
I block these calls with Youmail which is free. They use several phone numbers and one big scam is...send us $350 on green dot card and I will give you a loan for $10,000. I never applied for any loans. Most numbers they use are "phished" phony numbers so if you are stupid enough to give money you will never be able to track them.
