Transunion rectifying my credit record is taking far to long

Good day

I am not happy with my credit record at Transunion. Standard bank are placed twice on my record affecting the dashboard reading. The account is also up to date. but on One is showing arrears and on the other one it is handed over. Both have different info on it but it is on the same account number. I do not believe it is a Standard bank error. I have sent in several request to have this rectified, just no response and all this has to be done on their website. This has been going on for a few months that I ask them to take the one off. I pay a monthly fee for their service and expect results if asked to please assist with a problem, I would love to that Transunion just look into this because overall their services are good, just I am struggling to get my record sorted out.
