Poor service provider

TransUnion is the worst credit bureau. I logged a dispute for them to remove closed accounts and they responded to my dispute two days after with the same accounts still reflecting. Other credit bureau's have updated accordingly but Transunion is just useless, I don't think they even followed up to check the accounts but rather they decided to send me the same report without any update. They even dare and refer me to the credit OMBUD as if they've done the job on their side. I can't believe why companies still rely on useless Transunion for our information!
