Who called from 6369704415

I got a call from this number. Didn't answer. Voicemail said he could lower my interest rate on a credit card I don't have.  I live in 502 area code.

This was the exact same thing I got but I missed the first part cause the message started before my voicemail started recording.

Got silence, then a guy saying 'yeah, he--' then it hung up. I called back, it rang then a recording came on saying that the number was disconnected. My area code is 215.

Got a call from this number got a Yeah hi and then nothing and disconect. Called it back got a not in service. Is this some new way of taking my number for there use?

A man said Hello then the call ended.  Very shady...
