Renault Service Sucks!

It is quite amazing how people just ignore the fact that one has a problem!!! On 16 March my vehicle was towed to Renault PMB - diagnosis: Loom damaged by rats. I was assured that the loom is on back order and that it would take approx 21 days to get and install. I contacted my insurance who said they would foot the bill - I had car rental till 22 April (30 days as per my insurance) On Monday 20 April I contacted Renault who said the part would be here by Wednesday and the car would be ready by Friday. Long story short - it did not happen! (I had paid R250.00 per day for a rental vehicle from my own pocket) Phoned the dealer principal who refered me to the complaints line who came back to say that the part should be in South Africa on 4 May - PROBLEM!!! How do I get to work or should I just not go to work and not be able to pay bills - this will be the last Renault I buy and will definitely advise people against buying a Renault!!!
