ZERO ability to get hold of them/incorrect info on my credit report

I am absolutely DISGUSTED. Out of the 4 contact numbers you can find for Experian, either on their own goddam website or on Clear Score, NONE of them work. You're either put on hold by a recorded message that plays over and over, or the line simply says it's congested and hangs up. I received a credit report update that has incorrect and potentially ********** accounts/enquiries on my report, but who is there to explain, correct or assist? Absolutely no one. I want Experian to please rectify this immediately as I will not have my good credit score affected because of your incompetence.
