Documents were uploaded. Handset pick up was made by Airtel on 11th July 2018. Airtel secure asked to make 10% payment . And immediate I have made the payment. Airtel secure team called me and confirmed that payment has been received and within 7 days handset will be repaired. Airtel informed that there is liquid damage . I gave feedback that due to crack liquid might have gone there. Also I raised following questions .
Q.1How Airtel states that water ingress has not happened between date of reporting incident and date of collection of handset? How technical team has qualified that there was liquid damage before collision and not after collision?
Q.2 How Airtel has arrived at Conclusion that water ingress has happened before incident date ?
