Dear sir/madam
To whom so ever concern
I purchased the coolpad note 3 lite mobile from Ebay store online on 16 Sep'2016. it was in good condition and was working fine, recently when plugged the charger to mobile device
it was not displaying anything on the screen, but only LED glow during charging.
Due to this issue, I visited your Cool Pad authorized service center 'Vision Tech Enterprises', Pimpre Pune ( Maharashtra). for the mobile problem to get it rectify, they took the mobile set and created a job sheet (JS[protected]) IMEI : [protected] and later responded me, it will cost around Rs. 1750/- to rectify the problem and it should be bear by me.
My request to you, my mobile is under warranty period, and found no problem in the accessories, why I need to pay the money to get it rectify. I'm not going to pay any money, as it is under mobile warranty for one year. I have attached here copy of invoice for your clarification.
So please treat this with high priority and solve my problem, get my mobile in full working condition. I will be grateful to you and to your brand mobile.
Please reach out to me (Mobile No: [protected]), if required for more information,
Thank you
