Incorrect credit information. No response!!!

My Experian credit report is incorrect and I have send a couple of emails to Experian to have this corrected. To my surprise, no one replies my email and not even an automated reply with a ticket reference number. All I am asking is for Experian to correct and update my report as it is showing that some accounts are still open and behind but the fact is the accounts were closed more than three months ago. I have contacted the credit providers already and they have said they are going to contact Experian but they advised me to contact Experian directly to have this issue resolved. Can someone please help me?
