ITC Report has incorrect personal details and they dont want to assist in changing this.

Tried getting a Free Report from Transunion. However, when i received it, all my personal details were incorrect and some even required updating. I am now told by GAVIN via Transunion Whatsapp, that one must subscribe first to dispute the details on the report!!! Its supposed to be FREE... I have tried making the changes on the form, but it doesn't accept the changes. I called their number several times since 8am this morning... but calls get routed elsewhere and I am left hanging. I contacted them via email. The details are still wrong. i contacted them via Facebook and still no help. How does one submit a report with errors on it... Does it make sense Transunion???
