The WORST Financial credit provider in SA,

The WORST Financial credit provider in SA, I’ve come across. Im struggling to get hold of this institution no direct contact number. I've emailed numerous times. Used the chat box as well. I've settled the account on the 18th September, paid. It is now the 25th of September and no communication from Marquis regarding my Natis and no communication regarding the actual settlement of vehicle. The agents on chat box has literally stopped responding today. This is frustrating!!!!! I require feedback to finalize the licence of vehicle. I need someone from this institution to call me back and have this resolved today
