I have a collection item reported in my Equifax credit report. I tried to file online dispute but their website does n't work. You can fill out all info for an item in collection but can not submit the dispute. I have tried it for XXXX and finally called them. They advised me that I will have to use the online form to file a dispute. 

With non-functional dispute website and not responding on phone, I am left with no option but to file a complaint.
