No parts

I have been shopping around for the part (oil sump or oil bucket)since last year 27th Nov 2017 and I was told the parts is not available in the Renault SA. I then ordered the part on the 23 Dec 2017 and I was told it will delivered after 21 working days to date the part is not yet available in SA. I bought this car hoping it will address my transport problem since I am working on shifts. I am sick and tired of paying Uba everytime I knock off late. I also find it useless to pay for the car which is not fulfilling its purpose. Renault must tell me what must I do with this white elephant?? Renault Woodmead is where the part was ordered, I have been communicating with Avinesh (sales consultant) and he is aware of my situation and sympathy won't pay the bills. Is it possible to take this car back and maybe find a way to meet each other halfway in terms of the account.

I can't take this anymore........
