They will **** you!and break your car so that you come for more business! I took my car for service. Few weeks later it broke down. My car never had issues and NTT didnt notice any issue during seevice. I took my car for repairs under warranty. They sent invoice to warranty then sent another invoice for R12 thousand to me. I said I dont have money and they said that was a mistake that actual invoice is R5 thousand. I called warranty and confirmed they NTT is dishonest, the warranty had approved the whole amount and the additional amount added by NTT was misleading. Do not even try them
