DISGUSTED CLIENT

I am totally disgusted with the total care less attitude with regards to the BRAND NEW NISSAN NP200 that we took delivery of on Friday. the battery light went on yesterday and was told the alternator needs to be replaced on this BRAND NEW vehicle, what utter nonsense. the manager Greg states that this is as per the Act and with his 24 years experience thats the way forward. the dealer principle, Trevor is too busy today to make an appointment to see us today. My concern is that once the "cooling off" period has been completed, what happens?? Within the cooling off period, its a battle to get a hold of the manager (after 5xphone calls getting cut and threatening social media) then I get a call within 5 minutes. This is an urgent matter to me, may not be for this huge conglomerate, who sells vehicles on a daily basis. To them I am merely a statistic. MY POINT IS THAT WHY DO I HAVE TO ACCEPT A BRAND NEW VEHICLE THAT IS DEFECTIVE AND NEED TO BE REPAIRED???
