Called and asked for me by [first name] (first strike--I don't have my name connected to the number called).
Asked who was calling--would not give name or organization's name, but kept asking for me by first name and wanted me to admit that I was the person by that name. (second strike--why so insistent about my ID?)
When I insisted on knowing the nature of the call (more than once without admitting to anything), the man hung up after saying he would only speak with [first name]. Obvious scam attempted and thwarted--but how did they get the number to call?
