Service Advisor confused?

My NP200 was making a humming noise. This was the only means of transport so took it to Nissan Gateway to have it checked out. Told by Service Advisor Ishwar Sukdeo that a component under warranty has failed. He said he has to get approval first before ordering the part and he told us to bring the vehicle back. He stated that it was safe to drive the vehicle. When I asked for a written confirmation that it was safe to drive vehicle, he sent me an email stating \we cannot guarantee that the vehicle is safe to drive". He ****. Also he made no attempt to provide us with a courtesy vehicle or transport to our home which was 90km away. Stranded. Only after pleading with his manager Riaan Brooks we managed to get a lift home. Thanks Nissan gateway for all the undue stress.<br> """
