Turbo ****rs

My son paid R8900 to fix his turbo.but when he got it back it was leaking oil so we took it back and they said we have to pay another R450 to check and re balance because apparently we bend something inside with I can't understand how that can happen.but in any case we payed the R450 and after a week we got it back and still leaking oil.THEY ARE DOING PEOPLE IN AND IS ****MERS.THEY ARE SKELLEMS BIG TIME
