HTC — Htc desire 826 dual sim warranty repair delay

Address:

Thane, Maharashtra, 401202

I purchased Desire 826 7 months back.After 6 months my phone's display stopped working, So I Submitted it to HTC's authorized service center on 19th October 2015. The lady at service center told me that the phone will be repaired by 8th November 2015. They never called me or informed me about anything. On 12th November 2015 I called customer care and asked about the same issue.They apologized and told that the delay is from their side and my phone will be returned on 25th November 2015. Its 1 month and 5 days now.According to them my phone should be returned to me by tomorrow. I tracked my ticket No. and its showing Still In Repair. Htc one of the leading mobile company is taking more than a month just to change the display of my phone which is in the warranty period. this is really unacceptable!! There is no reason for me now to be polite with the company. Absolutely the worst service and an insult for all the consumers who use HTC phones!!!
