I have maintained a XXXX credit score with Transunion for the last 9 months. I recently checked my credit score through the credit card Co ..., XXXX and XXXX. They let me e know that my score had dropped to a XXXX. I have had no new loans, always paid my statements on time! I called transunion consumer relations to get an reason as to why my the score had dropped.? I was given no satisfactory answer.
