My friend have purchased vivo y66 mobile in march 2017. It’s only around two months and his phone stopped working. It is under waranty but service center peoples are not ready to consider it under warranty. they told the cost of repairing will be around Rs.3000. His phone is cost around 14k. Since the phone is under warranty then why he should pay 3000. They told that the bill is fake. what is this . it is very disappointed foe him. he moved to a local reapair shop after that which cost him only Rs 250.
