MAGNITE Lousy service.

I recently purchased a MAGNITE. At the first rains the windscreen wiper made a juddering noise and rubbed on the glass on the passenger side. I called in to my local dealer CARTER NISSAN, Bronkhorstspruit to lodge a warranty claim. I was told that it would take about 7 days. Now over 2 WEEKS later I have had no feedback. I cannot use this vehicle when it rains. What lousy service!! I am now sorry that I purchased this vehicle.
