Who called from 4235930664

I got a call from my number to my number. Shortly thereafter, I got a call from this number. I didn't call back, but the close proximity of the two calls tells me they're probably connected to some sort of scammer.

answered from this number ,no response ,then heard hang up.

I received a call from this number. I didn't answer, and they left no message. I called back on Skype, and it gave me an error for an invalid number. Looks like a new scam since there are only a few entries so far.

credit card scam ask where they were located they hung up. beware beware

just called my cell.  I don't answer calls from #s I don't know.  Caller did not leave message
