Just got the same as all of the above. Odd and have been getting calls with hang up over the past 3 days. No, I do not owe anyone $$! Sounds like some sort of a scam.
The first time I called back, they hung up when I asked who they were. With the second attempt, an "Amber" answered the phone and when I told her I was the business owner she started her pitch. It was a cold call from "Small Business Network" offering a subscription/membership and their MasterCard.
