They called me and idk who they are or how they got my number I text them asking who they are and they don't reply

Calls and leaves no message. Has called several times.

More like a spammer/scammer. I asked them where they got my number and why they were calling. They said "those are very good questions ma'am. If I could show you a way to make $1500 more moeny per month, would you be interested?" I said no, the line went dead. I am on the National do not call registry, doesn't seem to matter.

I received a call from the above number three times. Each time I answered the phone it was silent on the other end. I could also hear a clicking sound.

call about a debt, have no debts

Said I had recently signed up for educational information. I don't recall doing so. The person I spoke with wasn't any more pushy than the usual people who call with stuuf like that, but am somewhat worried now that I see this number has a history. Is there anything I should be aware of?

Debt Collector:Immediately upon answering says that the call will be monitored, etc. When asked to identify themselves, the call was dropped.

Some asian person calling early in the morning.

When I answer, it's just a recording.

just rang and we have caller ID so did not answer, no message left
