Incompetence and failue to even answer their calls

I have been trying to get in touch with any customer agent from Experian now for the last 2 months to resolve an incorrect listing and status on my profile and it seems impossible to get anyone to answer the call. I have even waited for more that half an hour at one stage for the receptionist to answer the phone and yet still luck. I have tried calling more than a 100 times and have sent through more that 30 emails. All I receive is responses from the *********** staff stating that the account shows as closed on their side however on the report and the information that is being submitted to service providers states that the account is in 1month arrears even though it is closed.

I need this matter resolved urgently!!!!!
