Poor Customer Service

I booked a rental online on the 14th of April 2022. Cancelled the booking the next day at their branch at OR Tambo. I still haven't received my refund. Today is the 6th of May 2022. I called last week to have the matter escalated but no response or refund. Today I am told that country wide only one person can process the refund and that he is currently on leave. So when he is on leave all refunds should come to a halt and wait on his return ? How absurd is that. I then asked to speak to his manager and the call got hung up. What nonsense is that?

Terrible experience using them for the first time. Safe to say I will not be making that mistake ever again. I do want my refund in full and it better be soon.
