On XX/XX/XXXX I checked my Experian app and noticed my FICO score dropped XXXX points from a XXXX to a XXXX. Upon further investigation in the app, Experian said that compared to the reports from XX/XX/XXXX and XX/XX/XXXX In Bold letters it says The percentage of your accounts always paid on time has decreased by 5 % Then underneath that in smaller writing it says Your percentage of accounts with no delinquencies decreased, which usually means since your last report there is at least 1 new delinquency on an account that previously didnt have any. I am a XXXX XXXX XXXX so I am well aware of all of the factors that go into FICO scores. Experian is saying that I have a new account that is now delinquent that was not previously delinquent. I checked, double checked and triple checked every account in the Experian app and there was absolutely no new accounts with a new delinquency. I only have two accounts that are delinquent on my Experian report. XXXX XXXX XXXX  has ONE late payment that has been reporting from XXXX of XXXX. The only other account with any delinquency is XXXX XXXX XXXX. This account has been charged off since XXXX of XXXX. It has been in charged off staus for almost 3 years!! Other than these two accounts there is ABSOLUTELY NO OTHER DELINQUENCIES ON MY REPORT!!! I spoke to at least 8 different reps at Experian form the Dispute department, Membership services and the fraud department who all reviewed my report to my previous report and they all said they dont not see any changes to my report. They stated they do not see any new accounts that are delinquent. They said the only two delinquent accounts on my reports are the two previously mentioned accounts and those have been delinquent for years!!! They all said they can not tell me what new account is delinquent because they dont see anything! And because they dont see anything on the report then its nothing they can do about it. I even spoke with FICO and they also said they dont see any changes to any accounts on my report. No new delinquencies, nothing has changed. But for some reason Experian is saying there is a new delinquency on my report and they are reporting that new delinquency to FICO which is going into the FICO algorithm which resulted in my score dropping XXXX points even though there is no new delinquent account on my report! This is very frustrating and Ive been try to get this resolved for 5 days now just for everyone at Experian saying they cant do anything even though Experian is the one who reporting this inaccurate information to FICO! I have worked really hard on my credit and this is absolutely ridiculous and unfair that this company will do this to me. I am in the process of qualifying for a home loan and this inaccurate information is greatly damages my opportunity to qualify for this loan. I need this resolved ASAP! I spoke with someone in the American office who said they couldnt do anything and she said a supervisor would call me within 24-72 hours and of course I never heard back from anyone. This company clearly doesnt care about the FCRA because they are reporting to FICO information that is false This needs to be resolved immediately or I will pursue legal action!
