vechicles not to be bought from xquisite auto

I have had the worst experience buying a vehicle..purchased this vehicle under 6 months from xquisite auto and in just a week occurred mechanical problems i brought it to the salesman's attention a week after purchasing the car, where he did nothing about it and said his boss cannot fit the bills,only to find out this sale man has resigned. so i personally contacted the boss Yusuf jeewa who himself said he knew nothing about the compliant \ i quote he **** "i asked him for a refund he said no he will do repairs on the car. Yusuf has taken my car in an occurred more problem such as electrical problems the breaking of the car Bonnet"
