Bad customer service

I won't recommend this place to anyone. I have taken my NP200 in which is not starting. No one called to tell me what's happening I hard to call them, they said it's injectors they have taken them for a service now it's been a month no call or updates. I tried calling on Friday and I have sent an email but nothing so far. I'm not sure how they conduct the business if there's not update. This is bad... It's gonna be two months now my car it's in the but still no update.
