I trusted them and purchsed it but unfortunelty vechicle breakdown on the same day in the eveing near by Faridabad. I called the Dealership and from there mechanic came and Reslove the issue of battery by saying that Vechicle was standing and battery got drained and prmoised me that no prblem will arise further.
