Due to the bankruptcy of the company I worked for I defaulted on my agreement with the IRS. The IRS put a lien on my property. A few days later my credit score dropped more than XXXX point. We spent the last few years cleaning up the problems and the IRS removed the lien and the credit reporting agency, Trans Union removed the record but my credit score did n't go up an iota. It is a one way street looks like. I know that it took an act of congress even to get to the point of them removing the record, but if the score is n't changed than they are showing a finger to the lawmakers and indirectly to you. 
Please investigate the matter. If you need more information I am more than happy to provide it. I do n't think I am the only one with this problem.
