Experian is not contactable, Unable to dispute listing on my profile

The business is practically not contactable, I emailed a billion times, a person by the name of Wendy Piet, keeps asking me the same questions and she is not helping at all. More frastrating is the fact that their listed contact number in not in service been calling the number 110 times a day with no avail. They are quick to list us but when we want to dispute there is no help. I am unable to login to my profile i have since changed my cell phone number that i used at registration. I am unable to login because the OTP gets sent to a number i no longer used there is no way to update changed cell phone numbers. Wendy is not helping at all. let alone that she responds when she feels like it, not that her response is of any help. I am tired. I even thought of going to their offices in stellenbosch only to find out that they dont help with consumer queries in the office No clear contacts, listed contact number never works, I tried a million times to call for help. emails are not helping aswell
