Got phone one plus 3 costing 27999 on 19.09.2016 and it got damaged it was in manufacture warranty and when checked with customer care they are saying that nothing can be done.
Please do something on it as we have paid a huge amount and it is just a month old phone.
Please refund our money or get the phone replaced else we need to go to consumer forum as there is still the warranty.
