[Resolved]  Samsung India — issue regarding my samsung galaxy s8 (sm-g950fd)

Address:

Chennai, Tamil Nadu, 600034

I've pre-booked my samsung galaxy s8 (Model no. Sm-g950fd) through samsung eshop (https://shop.samsung.com/in) with order no.[protected] and got it delivered on[protected]
As there was poor fitting issue of screen the service center (Techno care) at tambaram west have replaced the screen
But i was dissatisfied with the way they handled my device during service cause they scratched my device's backpanel and fingerprint sensor, they created all the mess that dust got accumulated inside the rear camera,
I've said them the screen i received was defective which was clearly visible as there was reddish tint which resulted in screen dimness but they just denied it without even comparing it with other samsung galaxy s8 and when i compared it with other friend's s8 difference was clearly visible i. E. My screen was reddish compared to other s8,
The factory fitted screen and replaced screen both had same issue of reddish tint so its clear the issue was on motherboard side
With addition to reddish tint the replaced screen had screen discoloration and its visible when using device under sunlight and i've attached images of same highlighting the defects for reference.
The device is also getting heated a lot and to an extent where i felt it may get blasted and with that fear i'm switching off the device whenever the abnormal heat occurs and its happening repeatedly on regular intervals. Is that for such kind of abnormal product i've spent such huge amount of money?
In the starting itself i've asked them to replace me the device or refund me the amount by taking back my device to which they denied saying its against our policy. Then "not handling the device in good manner when submitted in service centre" is it their policy? It should be returned in same clean and neat state by resolving the issue right?
And after that i was totally afraid to handover my device again in service centre to get the defective screen problem (Screen discoloration) rectified as the first time experience was very worse, so i requested for device replacement many times by contacting customer support but i was unsuccessful.
But now the issue got bigger the screen discoloration got spread across the display panel in many spots which makes me irritable to use it in sunlight and device gets heated up abnormally to an extent where i feel it may get blasted, the battery backup too is worse that it has become difficult for me to manage during travels. By stating the same issues i have submitted my device in tvs electronics valluvarkotam service center with job sheet no. [protected], imei no.[protected] and they just denied saying the same thing there's no issue! I've shown them
The proofs too i. E. The images attached below and i said them to check it out in sunlight too if they don't believe me, even then after knowing that the problem exists they denied to provide me screen replacement by saying no issue exists and for battery and heating issue they didn't even care to listen to me. Who will take the responsibility if it gets blasted someday?
And nowhere they mentioned or informed me about conditions if defect arises after service.
Now i need the screen replacement, battery replacement, motherboard replacement as they are causing the issue or else i need refund of money that i paid for device or they have to provide me with new device.
