Blacklisted for nothing - payments up to date

ABSA put an ITC on my name for my car payment being in arrears for 9 months. NOT! All payments are up to date. I confirmed with ABSA, and I have my latest statement indicating nothing is in arrears. I phone ABSA, they directed me to TRANSUNION, who redirected me to another department in TRANSUNION, just to be told I need to log a claim with ABSA. Again, phones ABSA. Now I need to write a letter asking ABSA to give instruction to TRANSUNION to remove the ITC from my name as it should never have been there in the first place. This is unacceptable! The entire process can take up to 2 months. I need to basically take control to fix a situation that should have not existed. Very disgusted! I could lose the house I want to buy due to, as I was told, \Someone did not do their job". Fix this ASAP please."""
