Nokia India — bought a new mobile nokia 6.1 plus- service not complete

Address:

I want to know the current status of the job sheet, since the Nokia 6.1 plus was bought through Flipkart on 21.10.18 and within 11 days it had a network problem, so I contact Flipkart to replace my new mobile, but they refused to replace and also told to contact Nokia service, I put a job sheet on 3.11.18, ( enclosed)and the target delivery date is 10.11.18, but till now I didn't get my mobile, so I contact Flipkart so many times to revert my money back, and also contact Nokia so many times to send the parts or otherwise swap it and give the new mobile, so I request you to give me a solution imediatey
