Unacceptable customer treatment.

I bought a new Nissan NP300 in Feb 2017. It has vey low kilometres. On 1 April 2018 a light appeared in the dashboard as a potential warning sign of damage. I took the vehicle to Nissan Clearwater on 2 April 2018, and since then I only hear from Nissan when I contact them. Today it is already 53 days that I have to do without a vehicle that I have paid for, which is of no use to me. This period of time without my vehicle or any feedback and explanations to me is beyond any reasonable levels of tolerance.
