Unhappy with repair work

When I got my car back from repairs, the aircon and hooter didn't work, the badge on the left front door was missing, the bonnet was not fitted properly and the car had a scratch at the back. They said I should bring the car back on 27/02/16. I took the car to them again on Saturday for the re-work.Their driver brought the car back in the evening, the aircon, hooter, and the scratch were fixed, however the badge was still missing and the bonnet was not fixed. There was further damage to the inside of the car by the door frame of the driver seat which was not there when I took my car in that morning. They said I should bring the car in AGAIN the next Saturday 05/03/16. On 05/03/16 I took the car back to them, they adjusted the bonnet and put in the badge that was missing. For the additional damage they caused on the driver seat door frame, they said they had glued it on as a temporary fix and have ordered a part to properly fix it. Furthermore, I have noticed that the paint on the bonnet is starting to rust as I drive in the rain. I sent them an emails to inform them of this as well as follow up the outstanding work they have to fix. A month later, still no response from them.
