I have mailed Experian dispute letters on XXXX XXXX, 2015, XXXX XXXX, 2015, XXXX XXXX, 2015, XXXX XXXX, 2015 and they never did an investigation? They never said anything was frivolous? This has to be a FCRA violation. Are they legally allowed to do this? Do they save money by not doing their jobs? Plus I have to repeatedly ask for Experian to correct wrong names, address 's and social security numbers I have no idea who or what they are? I have been told this is a really bad thing to have on your credit, is that correct?
