Experian adding bogus accounts on my profile

I complained about Experian an some outdated accounts were removed but the left one the SmartI don’t know about and added MBD I do not owe. Shouldn’t some investigation be done before a bogus account is added to your name. So basically anyone can just decide that I owe them therefore they need to appear on my account. I wonder if you’d do the same for a Pieter or someone with a better account balance. I will fight you with my 2 cents, that you can be sure off until you do right by me and many others like me. This unfair treatment needs to stop. The next step will be the ombudsman
