Poor Customer Service

In Sept 2018 i discovered that there was incorrect information placed on the transunion credit bureau website. the first being the merger of my information with my twin sisters information. At this point we both called and lodged a dispute, and was asked to submit documentation. all of which we had done. this continued for a month and still nothing was resolved. further to this i also lodged a dispute for a judgement that was against my name, and submitted the paid up letters to transunion, to date again this dispute was not solved. from September 2018 to now, i have not received confirmation of this issue being solved. i was only told that this will take 7 days however when on my profile when i login in, it is still incorrect. how long does it take a credit bureau to update information. especially since all documents was submitted. who ever is handling disputes never responds to the customers, you cannot phone in and check on your dispute either. i fail to understand why this is taking so long. i have emails and made numerous calls but to no avail. i wish to express my utter disappoint in transunion and how they are managed. as a customer you cant even escalate issues like this to management as they are never available. i hope for this matter to be resolved and the corrections made. this has been far too long to wait for errors to be corrected, which is on the part of the bureau and not the customer.
