Poor customer service

I purchased a jeep wrangler 2.8 CRD 2016 model around September 2018. My sales executive was Muhammed Bismilla. I collected the car without manual books neither maintenance manual. The guy promised to send them via post of which he never did till today( 12/07/2019). He also told me that the car maintenance plan is expiring August 2019, only to find out today 12/07/2019 whilst taking the car to service at Fiat Chrysler Sandton that Muhammad **** to me. According to the records maintenance plan of the car expired 30 june 2019. I then called New vaal looking for Muhammad only to find out that his no longer working there, now m stranded the car it is due for major service which cost R 12000
