Trans union quick to update your records but dont confirm first

I logged a dispute with them in December wrt. a Tracker account that was not mine and showed handed over, after receiving confirmation from tracker and Tracker sending this information to them on the 5th of December 2017 they still have not updated my records, I then logged a dispute in December around the 12th with all documentation from Tracker and myself, this now shows that the dispute was logged on the 22nd December 2017 I was not even in SA then, now I can not apply for any credit because of the dispute resulting in me loosing out on a deal. I feel that credit Bureau should confirm with the customer as well before just adding information to your profile... thanks for not resolving my dispute!! this has cost me a lot of embarrassment and a good deal and the call center is of no help.
