Different colour paint

My name is mzwandile Zulu, I took my car for scratches and dents to mastercraft Autobody in Durban on the 31/10/2017 When I fetch my car on the 06/11/2017 I found that my car was dirty, when I took it to the car wash I saw that the right front door that they painted is not the same color as the car. They also file the back door handles and I have no idea what was the reason for that. I'm so disappointed with their work and I will never advice anybody to take their car there. M Zulu ********** 502
