BAD SERVICE , UNFAIR TREATEMENT

This is ridiculous service!!! I booked an exam for the 13 January 2025 , an incorrect reference was used, i called on the 6th to rectify , it was escalated to one of the agents called Marietjie Grant, i did respond back to the agent with relevant information and pop with the dates on the same day. I have sent numerous follow ups with no responds. Bad Service Moonstone
