Update:
16/9/23 - To my surprise, I received QC today, much earlier then expected.
17/9/23 - I've green lighted the QC and paid the remaining balance via Wise. However, Steve is stating they haven't received the payment yet, however, Wise suggests that the payment has been complete. This delay could be due to weekend banking delays. Steve and I will check in again tomorrow to see if funds have been received yet.
It might be worth noting, the payment details provided for the deposit and rest of the payment were different. I clarified with Steve and he said I can pay to either payment account.
