HTC India — Not repaired under warranty

Address:

Kota, Rajasthan, 324006

Dear HTC,
I purchased a HTC mobile handset from Krishna Enterprises, Kota on 28th May 2016. Initially mobile was working fine, but at 7th July 2016 I''d a network problem, I took it at htc service center on 9th July 2016 as it was closed on 7th and 8th July due to eid
At service center they were unable to solve my problem and they told me that this mobile will be sent to jaipur service center for further repair.
Then on July 14th 2016 I received a phone call from service center and they asked me to pay Rs 8500 for repair of a Rs10, 500 mobile. I told them that mobile is under warranty but they said that it is internal damage and not covered under warranty.
How could a mobile get internally damaged when it is under warranty and even when mobile screen which is most fragile part is not broken?
They also told me that battery connector was loose.
How could they manufacture such mobile which of no reason gets internally damaged.
This is my second HTC mobile and I am not happy with the service provided. Mobile was hardly 42 day old and it had such serious problem. What would I do with that mobile when it cant detect network nor could I spent 8500 on that piece even though it is covered under warranty and I''''d used several other mobile of other brands and no company at the time of service said that it is internal problem which happened due to customer misuse. Also they told me pay Rs200 for service and handling.
I now cant figure out the reason for purchasing branded mobile and warranty period.
I request HTC to consider my complaint and repair my device under warranty for no extra charge.
