Deposit *****?

To be able to take part in We buy cars online auction, I had to deposit R4000 first. The eft option did not work, so was forced to do a ozow transfer. After the auction, as I did not get a vehicle, I asked for my refund. Then I should learn that ozow refunds can only be done after 3 months! I sent an email in this regard, asking for my refund, or if not, at what interest rate will my money earn as per law when deposits gets withheld. We buy cars did not respond at all, therefore this report here. Do some maths, how much money in interest do we buy cars make from the deposits that gets withheld from their customers.... I will be making a Hello peter report daily, until I have recieved my deposit including interest back from we buy cars.co.za.
