Thank you, read the article - didn't really answer my question but thanks

Hi All, Need some advice, I'm contesting a Cat 6 CIFAS marker on my file by NatWest History In 2012, i was the victim of fraud, which involved fraudulent cheques being paid into my account, then cashed out. I contested this fraud to Natwest, however they rejected my appeal; I escalated this to the Financial Ombudsman, however they sided with Natwest. Now I tried apply for a credit card with my bank (Barclays) but was turned down; this prompted me to investigate (currently have a Credit Expert score of 991 and earn £50k+) as I should have met the criteria. Upon investigating, I found out that NatWest have placed a Cat 6 - Third Party Fraud marker on my file. I've contested this with Natwest, however they believe this marker 'is a true reflection of my credit file'. I'm currently in discussions with the Obudsman regarding this; I either want this marker removed or changed to 'Facility Takeover'. I would love any tips or advice from anyone on how I can deal with this or how I can get the FO to side with me. (p.s. I'm not contesting the fraud as I can't contest this again, this matter wasn't in my original complaint in 2012 as I wasn't aware of it) This marker is casuing me major issues as I'm unable to apply for credit or open new accounts, so the mortgage I wanted to apply for this year is offer the table. Thank you in advance for your help
