SOLD WRITTEN OFF CAR

I bought Suzuki Swift 1.4 GLS Automatic from WE SELL CARS on the 7th December 2016, Kobus was the Sales Rep responsible for the car. My car VIN JSAFZC82S ********** 4 Engine number KB14B ********** . Recently on the 27th December 2017 I started to have issues with my indicator and I took a car to Suzuki Dealership to check it, to my surprise I find out the vehicle is written off. Kobus never explained this to me when I first bought this car, I never had any copied from him till today about the vehicle history.I am unhappy about the level of service I received from WE SELL CARS, I have original document from Suzuki that support that the vehicle is written off. I am driving a vehicle which was rebuild and i was not even aware of it and my insurance is not aware of this also.
