Incompetance of staff members

My Car went into Renault Benoni on the 22oct because my key was ******!i was told i have to wait 21 working days for a new key,because it needs to be ordered from France!i waited till the time period was over and got no phone call from no one until i decided to phone in my self because i need my vehicle and cannot lend the vehicle that i am currently using any more.then i was told the incorrect key was somehow ordered and try and spin me a story that these things happen while i am working in the motertrade and deal with these things every day and know a fault like this is due to incompetance!i phone benoni renault and ask to speak to a manager because i need a curtacy vehicle because the key is incorect due to a fault from their side and i am sitting without a car.they say they can only help me in january which is rediculous!i phone Renault Sa and spoke to Leo and he at first was not very interested to assist me then he keeps telling me he will phone me back very soon but never does!when i phone a day after he comes and telle a wipermotor is on order!Renault is fast to sell you the car but from there you are on your own!aftersales is terrible to say the least
