Bottom line, it's a telemarketing scam. The message they left contained this number, 8882614660, which has plenty of comments associated with it. None of them good.
I got one from this number around 8:10 EDT today. No caller ID on my system for it, no one answered. But recent comments that people have posted on a similar number (406-426-3124) suggest that it's probably a scam of some sort.
I rejected the call and it went to voice mail. The beginning was cut off so I didn't get the company's name, but it's one of those outfits that claims they can consolidate your credit cards and lower your interest rate and monthly payments. They're fishing for victims - er, clients.
Looks like they've been busy. Got a call from 406-426-3035 at 10:20 EDT, but did not accept it. No voicemail message left. Caller ID said the call was from Montana.
