Unfair treatment

On the 17/06/2021 I send my dispute papers to this captured credit bureaus which is Experian and compuscan. I waited for them as they take about 20 to 21 days to resolved the matter. After that 21 days I called them only to find out they never bothered to remove those accounts which was opened on my name **********ly. When you call them you hold over 45 minutes to prove how bad they are. When I speak with them they want me to give them a payslip and a bank statement which I don’t have because this happened way back. What I see to this credit bureaus they don’t help or they are not neutral because they should investigate as they claim but they take you pillar to post as if they working for the shops. I don’t have those payslips and those bank statements because I closed those accounts. Why must I produce a payslip where as I don’t open an account. I am not happy at all. Please remove those accounts from my profile because I never had, unless this itc’s are on the company’s payroll.
