Who called from 3216328549

Scam.

It's the old "you've won a free cruise" Travel scam.

Same scam, different number.

Unsolicited, unknown call. No message left.

Probably spam, there is another number very similar 321+632-5642 that has a long history and they are probably using this number now.  I suspect it's spoofed from a foreign entity that is spamming or phishing.

Thank you for the info; I just received a call from this number in my cell –since I did not recognize the number—I did not answer it and will be included in the spam contact with silent ring tone.

just got a call from it too. didn't answer as i didn't recognise the #.
googled it & found a long list of hits concerning this #.
