TransUnion - Incompetence

I've been struggling the clear my name (ITC) for more than 2 months. After supplying the documents from the company that listed me, showing that I was incorrectly listed, no progress have been made.

After applying for a home loan, I discovered that Old Mutual Short term insurance listed me at TransUnion (ITC) and Experian in 2022. I was unaware of this, as I bought a new car and app**** for other contracts afterwards, without any issues.

I contacted our broker (3rd party) who supp**** me with 2 files from Old Mutual Short term insurance, proofing that I was incorrectly listed, which I forwarded to both TransUnion and Experian. Both companies requested the documents from Old Mutual, my ID and proof of address, which I sent through.

After about 2 weeks, I got feedback and a document from Experian, showing that my name was cleared. Unfortunately, on the June 19, TransUnion requested the same documents again (after I sent it) and 16mins later the following message: "Due to insufficient documentation received by TransUnion for TU*** the issue has been closed. Contact TransUnion to lodge a new dispute/query".

How do I resolve this issue? Is there someone from TransUnion that I can contact, as the number and email address on their website, clearly doesn't help? We are pressured for time, as the contract that I signed with the home seller, is about to expire and will I lose my deposit of R100 000.
