Worst experience - waiting for refund

I was pressured by an agent to pay a deposit on a vehicle while we apply for the finance... Paid the deposit within a few minutes of him sending me the baking details, only to find out the next day that another agent also submitted an application on the same vehicle. Ok fine - these things happen. But that was the first annoyance.

We then app**** for another vehicle with another branch, but by the time they sent us the Offer to Purchase, they had added about R24 000 worth of additional charges. So we cancelled the deal.

I am now trying to get a refund on my R5000 deposit. I have emailed, I have phoned, and I followed up. This has been going on since the 15th of September. I am at my wits end.
