Karbonn Mobiles — service center not repaired my new smartphone still

Address:

Dehradun, Uttarakhand

i had purchased new karbonn titnium s1 plus from Chandigarh the after 5 days display gone blank, and now i have given this mobile to my nearest service center(detail in the attachment) to repair the same from last 2 months, but it is still not repaired .and in future i will never prefer myself or anyone to karbonn smartphones. Please solve the same as fast as possible rather i have to go consumer court taking Karbonn warranty no claim issue very poor service.
