Recent Free Phone Number Reviews in Area Code 510 2xx

Lynda (blitzgurl125@hotmail.com) commented on 510-274-2022
This review was created at 2011-11-28T23:55
I received a call from this number but did not answer. A voice mail was left instead. According to the voice mail, the caller was a man named Joseph of Frontier Financial Group. He was informing me that he was performing an audit and this was an attempt to collect a debt. I have received many different messages from Joseph all asking me to call him back at (877) 683-5490. This is a SCAM. I have looked up the 877 number as well as the company and have found a great number of people have received the same calls and have verified that the company is only seeking to cash in on your personal information. If you receive a call from this number do NOT call back to verify information.
