Disputes not resolved, calls and emails unanswered, credit report ruined

Experian has done it again, no matter what time of the day you call, you will never get an answer, no matter how many emails you send you still get no answer, now my report has new "old" debt that is 4 years old and prescribed, can you please remove the record (Finance 27) and block it? It was removed twice and now its back without a warning, i did not even receive feedback for my disputes. How does one contact experian? Or do we have to use social media and ombuds as our communication medium? If creditors and collectors have special lines to contact you and update our details sure we are entitled to that too, someone needs to be fired at experian, maybe even the entire current stuff. How do ylwe lay a formal complaint to have this company reviewed? Anyone help
