Not even one is suitable for this. But we don't have option to give zero. I was given my HTC Desire 616 for service they said software corrupted and it will be done in 2 hours. Its already evening hours so, they ask me to come and collect by tomorrow. I visited their delivery center by the next day, their answer is the phone is with back end team you please consult to the person with whom you was given. Again I went to the person and I spoke with them. what they are saying is go and check with delivery people. No proper response and they was provided one contact number but its always busy.
