Unable to find a way to file this type of complaint through the dispute system for Experian. My credit score dropped from XXXX two weeks ago to XXXX this week. There is no reason documented in my credit report why it should have dropped, all XXXX of my credit accounts are in good standing and never late. i have been paying XXXX accounts to XXXX every month. There are no major inquiries into my credit. There are XXXX old old negative accounts due to a real-estate short sale in 2010 but they have been accounted for all this time. there is no indication as to why is would have dropped. They keep mentioning that missed payments are the biggest reason for drops in a credit score, but i see no account or know of any account where I have missed a payment or was late on a payment. I would like to have a reason or have my credit score restored to the XXXX that it was before. Thank you. -XXXX XXXX XXXX
