Bought Porsche

I bought Porsche for just a few days and very unfortunately within a few days the car couldn't start. The dealer ask me to send the vehicle to O****a W**kz. After leaving the cars there for few days they still can't tell me what's wrong. After repeated followups, the car end up in the shop for around a month and couldn't tell me what's wrong. End up I pay an adoption fee in agent and surprisingly the car was done in a day, which is only a fuse problem. I didn't understand why the company was not able to solve my case. No matter how big a garage may look sometimes looks can deceiving.
