Coolpad India — Worst durable products

Address:

Sir,
I have purchased coolpad note 3 lite in the month of may 2016 through amazon india. From the date i have started using the phone i have been facing several issues like hanging up. I have gone several times to service centers but their response is minimal. Whenever i went to service center to report an issue they did not even filed a job sheet stating it as a common issue in coolpad. While this issue was on, suddenly on one day my phone got turned off. I again visited the service center and i insisted to file a jobsheet. On my request, they have filed a job sheet and after 8 days they telephoned me and said that the issue was with mother board and need replacement which would cost around 7000 (95% of phone's actual price.) which is abnormal.

Since, problem was with product and inefficient service centers, please solve my issue with mother board at the earliest.
