Called me too. Didn't say anything. It was an automated voice that said goodbye. I called it back and it said something about employment opportunities. Definitely a scam. I won't be answering numbers I don't know ill let it go to voicemail, or if they really need me they will call again.
I actually received 2 phone calls from this number. One occurred at noon today and another one came in at 7pm this evening. No message was left at either time. I will not answer number I am unfamiliar with.
Called me several times so called the number and it is some job placement place that claims i expressed interest online about job placement and this is bogus. Somebody sold my number:(
