Be carefull of dynamic boost turbos

I got my turbo repaired by a guy at dynamic boost turbos and 4 days later received my turbo back and was told its perfect now, R6000 later. After trying to fit it i realised my drain fitting is missing also realised the turbo has more play than it had before taking it in, so i called and spoke to a lady Simone and she refered me to a guy called Douglas who then said its my fault i did something to break my turbo. Also they do not take any responsibility for part missing, now im stuck having to buy new unit just up the road at MJS turbos who supplied me for even less than the cost at dynamics boost turbos. Please be carefull as i was told they dont have any certification on turbo repairs. Lesson learned
