Greystone Staffing

Review: I have been trying to reach Greystone Staffing for more then 2 months, and when I call it is a standard answering machine. I have left over 20 msgs for someone to call me back and no one has called me back as of today. I have an opportunity to work for a prestigious company yet they cannot verify my former employment with Greystone Staffing. I have tried calling the contract companies I have worked for through Greystone Staffing, but by law they cannot tell me when exactly I worked for their company, I just get the run around and am informed I must call Greystone Staffing to get that information.I truly don't know how to get my own person employment information from them. I have tried the [redacted] and all I can get are my W-2's. This new company wants to know where and when I worked for each seperate company I was contracted out to through Greystone Staffing.Desired Settlement: I need to know how I can get all my employment records from Greystone Staffing.
