Transunion are shocking!!!!!!!!!!!!

The services from this particular credit bureau is shocking. The number of times I have lodged complaints about my credit information being wrong only to be told it has been rectified. I then go and check and nothing has changed. You have messed up y credit score so badly by having accounts that are in arrear that are not and they have actually been paid up. The accounts have never been in arrears. I have sent through countless correspondence to support that the accounts to say they have never been arrears but still 4 months later there have been no changes! You are absolutely useless!!!!!!!!!!
