This is a debt collection agency there name is Pinnacle Financial there purpose is to collect a debt a lot of phone carriers use them AT&T Verizon tmobile don't give them your info they will use it against you to collect a debt

I just got a call from 406-545-4356 and found the listing is in Montana.So I called them back because I have recently been conducting business in Montana and thought that perhaps one of the business entities I contacted in Montana was trying to get back in touch. The individual who answered  gave the name of Pinnacle Financial Group. I played like I called the wrong number. After doing my homework I found that Pinnacle Financial Group was in another state. My suspicions are that this company has been tracking my phone calls, found that I made several to Montana, so they procured a Montana phone number to lure me into calling them. Beware of Pinnacle's and others tactics like this.

This is a follow up starting at 4028585086 then 4054631570 and now this.  They are working up the ladder in the area code numbers.  Pure harassment.

This is a bottom feeder from Pinnacle Financial look for someone.  These people live off of your hard earn money if you let them scam you.

Dumb a** telemarketers keep calling.....again!...

Automated phone scammers. Wanted to sell me additional auto insurance. Others claim everything from them trying to additional protection on their credit cards to home security systems. I talked to the woman and she just kept trying to get me to give up my credit card information so they could "verify" me. The call is routed through Billings, Montana, but one report said they were somewhere out of California.
