TRANSUNION POOR EFFICIENCY WHEN UPDATING ACCOUNTS

My phone was ****** so when i attempted to open up a new contract i was declined by MTN due to outstanding Avon account that i had no knowledge of. They never attempted to call and they had a incorrect email address that they claimed they had tried to contact me on. I immediately contacted TransUnion who notified me that the problem was that i had defaulted on a payment for the account i had with them. I immediately contacted avon and paid the account in full. I am still waiting for TransUnion to updated my status. Until then i am unable to take out a contract. I cant believe it is so easy to be listed as a bad debtors but the process takes so long for us to clear our names once the payment issues have been rectified, I think the entire process is so unfair and ineffective. I'm relieved i managed to find this out now at not later when i decided to apply for a bond for a house. PLEASE CAN TRANSUNION UPDATE MY ACCOUNT TO SHOW THAT I AM ALL PAID UP!
