Please help the renault *****.

Unfortunately this is not the first time I've written on this site but again i sit with a battle with Renault SA(I C Auto Kempton Park) I purchased a Renault Clio 2017 brand new vehicle after owning a Renault Clio that I had no complaints with. 30000km my on board computer card reader packs up.Card Not Recognized is what it says after taking my car to Renault and being told that the part is not available in SA 3 weeks i must wait after arguing and begging for a loaned car as it does say on Renault web page if part not available loaned car will be provided after submitting my review on this site the following day they had a car available . Now I'm at 80000km and guess what part isn't working again now I've been told that ive broken the keys both of them and im liabel for the key at R3900-00.After 2 weeks of having no vehicle ive tried to trade my car for another one in order to get a car immediately.Only to find out that I'm on ITC for bad payment of old account that is nearly up to date. Nedbank credit card division who i pay monthly my car at moment is financed through and my salary goes into. only to hear from renault today no key has been ordered as i must pay for the key upfront which i still argued what is my extra warranty that i pay extra every month covering and i said at 30000km this would happen again and told not to worry its got a 90000km maintenance contract.Still waiting for renault customer care department to come back to me as Lucy's boss is on leave. all i want is renault to keep up their side of agreement get the key if i have to pay i will but may i have a courtesy vehicle please in order to keep my job .being a salesman on the road without a vehicle is very difficult.can renault assist me please as this is ridiculous at any level .Unfortunately I don't see my next vehicle being a Renault . Such a pity as i love my car .
