Coolpad India — Coolpad dazon1 dosen't show sim and having starting problem

Address:

Ajmer, Rajasthan, 305001

Dear Sir,
I have purchased coolpad dazon 1 android phone 1 year back, than after some time it doesn't show the sim's and also having starting problem, that means it had taking time to start approximate 5-7 minutes, and it also dosn't showing the IMEI no.

I was visited the service center 2-4 times but they just update the software and it would working good for next 4-5 days, but again the same issues appear.

last time I visit to center they suggest me to update again and i have to pay for it, also saying that if the phone's Motherboard short circuit, I am responsible for that, they are not.

Please support as fast as you can and give me the proper response. Because it spoil your brand name and value which I have trust.
