No feedback on blacklisted account

On 11/04/2020 I submitted an online enquiry to be given banking details in which i can use to settle my account since it reflects as a judgement on Transunion. I received feedback with reference no. 67YM0U7X stating that i will be contacted in 2 working days. Its been months now and no feedback from FNB. All i need is a bank account and reference to use.
