I have received two calls from Officer John Bright with the Federal Crime Investigation, one at work and one on my cell phone, telling me I owe $300.00 to an Advanced Cash payday loan company from July, 2010 and that if I did not pay this I would be charged an addtional $1500.00, they would take 154 points off my credit report and I would not be able to draw my Social Security benefits. He also told me that he would have to contact my employer. He does not speak English well and when I asked to speak to a supervisor or someone who speaks English he told me he was the supervisor. There was a lot of background noise of other people on the phones, all of whom did not speak English. When I questioned if he was from the USA, Mr. Bright said L.A. California. He had all my pertinent info such as last four digits of my SS#, e-mail address, address, and employer. I do not owe $300.00 to an Advanced Cash Company. What am I to do now? Can he really do all this to me?
