Called while I was working. Never answered and not VM.

Called .  I did not answer.  There was no VM left

Said they were from Customer Service and I'd won a "free" vacation.

Hung up when I answered as a business. They call often.

Scam, fake vacation offer, recording asks if you make more than $40,000 per year, if you aren't busy say yes, get directed to a person, let them read the details on the scam for a while, it wastes their time, act like you're interested, when they get around to taking your credit card number, they ask for your email address first, spell out whatever you want to tell them gof**kyourself@getajob.com or something
