I had purchased HTC 826 from local shop at Gwalior on 29.05.2015 the IMEI of which is [protected] and S/N is CC3MYG07383.After some days I saw some fine vertical lines appearing on my handset which intensified later on.I went to the service centre situated at Sanjay Complex at Jayendra ganj Gwalior on Aug 1. Since then I dont have any information regarding my phone.Kindly resolve the issue asap.The image of the brand has been put under the cloud and is depleting daily because of such poor customer service and handsets developing issue within their first month o[censored]sage.
