In April 2007 I signed up with amp'd mobile for their cell phone service. Two months after I got the service they went out of business and filed bankruptcy. After the first month I never received the bill. I called the company several times and their customer service was unavailable. In 2008 I started receiving collection notices for payment to amp'd mobile in the amount of over $6,000. There is no way that calling locally in two months I could rack up that amount of charges. I disputed the claim with all three credit bureaus and they were no help. I even called the credit agency to ask for documentation showing how I could possibly owe that much but they never got back to me. I am wondering what my options are seeing as though I know I don't owe that much. I want to sue them but I am not sure if I have the funds for that. I lived in Washington, DC at the time the account was opened.
