Same happened to me. Called this number 10 times no answer to find out about an outstanding fine.
Tried 6214 and 6212 after I asked for a different number since the first one showed no results… also no answer.

This number was given to me from the renewal drivers license department in Centurion Pretoria to phone regarding an outstanding amount against my ID. The name Mr Brown was given. I tried for 2 days now to phone the number, but there is no answer on their side.
