got like five phone calls from this number in one day.  never left a message. i answered the call the last time and it was a credit card company.

I had the same.  3 times i got this call in one night.  no message left.  I'm not calling a number I don't recognize.

Also received several phone calls from them over the last few days.  No message or contact info left and I do not return calls from #'s that I do not recognize.
