Varun Motors — behaviour towards customer in serilingampally service center

I am very much disappointed with manager, after 4 hrs of waiting.. When we want update about the process. He was like if you misbehave with me i will give police complaint and all. Seriously i am not here to listen this kind of dirt and # from manager over there. Beforehand we asked will you do it else we will be leaving. They assured us work will be done by d time. And behaviour was very disrespectful i have ever seen. I would request you to take probable action towards him. Thank you
