Dissatisfied Client

I bought a Renault duster that I love so much because of its uniqueness with lot of accessories. I bought in August this year at Renault fury amanzimtoti. On the 25th Nov I noticed that it was leaking water when it's raining. I called my salesman to inform him. He referred me to the person by the name of Lesley who booked my car in to be fixed and told me to prepare an amount of R1500 without even inspecting the car and know what causes the leak. I told her/ him that I won't prepare any payment because this is a brand new car and this seems like a factory fault. My car was then booked for 30th Dec and told in the afternoon that my car was no complete so I have to fetch it the following day, which I did. My car is leaking on the left side of its roof but when I fetched it, it had black taps on the right and I was warned not to remove them soon. Went away, few days it rained again and the leak was worse. My hubby took it back again on the 14th Dec could not be fixed on the same day and was booked for the 15th. He sent it back and was fixed brought back. On the 18th Dec it rained again and it's still leaking even today. I called Lesley again and She said she cannot book it anytime this week she can only book it next week. I asked if I have to keep a leaking car for the whole week that will result to more damage caused by the leak. She then said she will call me back. She then called me back and instructed to bring it tomorrow the 22 Dec. What I'm trying to emphasize here is that because the bank has already paid their money I the customer is left without being taken care of and I have lost trust in this company because of the way their representative treated me, but I have no choice to take a brand new car for repairs for the third time. This is really frustrating me.
