Poor service and **** refund services

Brought back the vehicle on the 26th of April of which I was over by a few kilometers and was aware there would be a bit deducted from my deposit. The process was not explained to me by the gentleman that was helping as to how many days it would take to get my refund. On the 7th of May I call to follow up on my deposit and was told they are now sending an email to finance to look into it and I should call back on the 9th, I call on the 9th and I’m told funds have been released and will reflect in my account the next day as I’m discovery back. 12th April I call again to tell them still no refund and Mandisa who misled me on the 9th started giving me attitude till I requested to speak to someone else. I’ve made contact with Nick the branch manager at Springfield/ escalated it again to Essa and still no joy, no talks of the money I’m spending calling being refunded. I’m spending more money trying to get my money back. I have not received my refund till to date the 18th of May 2025 which is 3 weeks later
