Worst service ever!!!

Nearly 3 weeks that my vehicle has been with them for something I was told would take 3-4days as they had to order the part. Had to pay a R6500 deposit for part. After 10 days I eventually called and was told they would call me back with update. Call never happened. Called again following day and was told my vehicle is booked for repair the next day. Now nearly a week later I was forced to call again and again was told they'll call me back with feedback and again no call back. Never again will I deal with them
