Disgusted by the service at the Melrose branch

Disappointed by the services that I have received from Renault. I bought a Renault Kiger in Melrose and I am currently based in KZN. The dealer charged an amount of R1500 on my Finance contract to cover the cost of registering car. I was told since I’m based in KZN and the dealer is in Gauteng, I will have to take out money from my own pocket to pay for the disk and the number plates and I would be offered a refund, fine as a human I understood that , I went to the KZN transport department on Friday did as told , now that is time to refund me , they do not want to pay an amount of R50 which will be used for installation of the number plates , they are saying I need to provide them with receipt of that. I am beyond fuming and I do not appreciate any of this at all, I have requested the branch on numerous occasions to supply me with receipts of how the R1500 that was taken from my ABSA contract was used since the purpose for which the money was taken for, I ended up using my own fuel and taking time off my work day to go to the transport department to do that myself personally, I need you to account for the R1500 by providing me with receipts, should there a balance from that money, refund all of it either on my ABSA contract or on my personal bank account it will cover the cost of installing the number plate as it should have in the first place, you cannot be asking me for receipts of my money when you yourself have not provided me with receipts of how this money was used, I will wait for your response, should you require me to recover this amount legally, I will do so , we clearly taking each other for a ride.
