I recently received my FICO score from Experian. It stated that a person 's score can either go up or down with this new FICO system. I looked down at my score ... .it went from XXXX down to XXXX ... XXXX POINTS! I called Experian. They told me that my recent charge of {$8000.00} on my XXXX caused it. I told them that I had paid the whole amount in full, and that my total credit allowance is {$30000.00} anyway. I only used up XXXX % of my credit limit, paid it in full, and now I am being penalized for it! I have never in all my years paid ANY bill late. Please tell me how to proceed to get my score back up to where it should be ... XXXX. As you can see above, Experian 's response was " final ''. I spoke to many people there, and no one ( even supervisors ) would help me rectify this situation. Your help would be so much appreciated. I am a XXXX widow ; I know if my husband were still alive, he would be reeling on his heels right now! He was a bank representative and very professional. He would never have treated his clients this way. 
Thanking you in advance.
