Rondebosch East Toyota

Took my toyota corolla for a normal service last month when I collected my car it has been cutting off no power at all, since then it has got a bad fumes smell. I have called the service manager and he refused to admit they messed up my car and even Toyota South Africa can't give me answers they are covering up for Rondebosch East Toyota. I would never recommend this Rondebosch East Toyota to anyone customer service is very very bad
