No customer service

I have emailed experian on the 15/09/2020 regarding an incorrect account listing on my credit profile. I have resent the same email for the last 4 weeks and have received no response I have also tried to phone them on their numbers listed and the call is just on hold for hours and hours with no answer How is one supposed to rectify errors on your profile if they do not respond to internet, email or telephone disputes. It has been more then a month now
