Previous employer refused to give paycheck and won't send W2

Please help me. I worked for a company for a very short period of time, however long enough to receive a paycheck. They lied about mailing my check to and after over two month stated they refused to give it to me. I asked for my W2 and they stated it would be mailed the last week of January. I never received it and have called back at least 4 times a week. I have been lied to and told it was mailed and was told it was mailed to two addresses when only one was provided. My personal information was sent out to a random address if it was ever sent out. They will not let me speak with the owners and I never get a call back. Please help me. I have called the IRS and they sent a letter and stated I can estimate my wages. This company has lied, kept my paycheck and sent my information to a random address.
