No one is following up or taking resposibility

I have had a horrible two months and really regret the day I bought a Renault car in 2014. The steering rack leaked all hydraulic fluid and I took it to Melrose Renault 29 October 2015,Alan(Dealer) told me it was ordered and its on back order meaning no one knows the delivery date gave me Renault customer service gentleman named Reggie who later told me he doesn't deal with parts I have to go to my Dealer(Alan) who sent me back to Reggie(customer service Renault) I then asked to speak to the person in charge of Customer service that happened to be Sharon and she said its not her problem and sent me back to Reggie, who in turn sent me back to Alan(Dealer) where I got a WIP number for the steering rack and was sent back to Reggie and told Melrose in no longer dealing with Renault. Reggie told me that my order will be delivered to Wood mead where I went and was told they never received any info regarding my vehicle. December I took the vehicle to Bethal Renault and Chris helped me with Leo(Renault ) to get a courtesy car,one week down the line I got a call one hour after the said deadline that I need to return the courtesy car and my vehicle is not yet ready. Amazing customer service!
