HIGHLY ANNOYED

My account was handed to their lawyers RL Daly. I settled the account in June. I also discovered that they had me blacklisted. I've been trying for the last two month to get WOOLWORTHS to update my ITC status. RL Daly says it's Woolworths responsibility, Woolworths is passing the buck to their lawyers. I'm trying to buy a car and I'm being declined due to this. Can someone please do their job and get this matter sorted.
