[Resolved]  Samsung — New product not working

I brought the refrigerator on 13th june 2020, was installed by samsung team next day with all the demo given. 13th to 26th june noticed the fridge compartment not cooling (Food getting spoiled) and raised an issue on 27th via phone.
1. 6th july service engineer comes home to check, within 2 mins he claims it is working fine and this was a false issue raise. On further asking him when both compartment are fridge setting and set at 2c why is top alone cooling and not bottom, he said top will always cool more and bottom wont. He also claimed this is inverter fridge and has this issue, you should have asked before purchase. He was ridiculously rude and rushed out saying it is false claim without addressing and giving a solution. Total time was 2-3 minutes and didn't check anything.
2. Post that 4 calls were made to customer care for the issue and repeatedly told that it has been informed to the service teams and they will send a senior person. On one of the calls the customer agent vignesh repeatedly says if there is an issue we will fix it. More like there is no issues and you are calling us. Why would i call after buying a 60k fridge and if it was working fine, does it look like all customers simply call without problems and we are wasting out time?
3. Finally after escalating on 15th again, 16th the same engineer comes to check who is rude and has no sense of customer service.
4. Same service agent comes on 16th, steps he does
A. Connect a error logging device into back of the fridge, says there is no issue
B. Checks temperature at 4 places (Bottom compartment top shelf - 5c, vegetable bucket - 7.5c, bottom compartment middle rack (Note: inside the fan holder itself, felt intentional, not ready to check where actual food is kept) - 3.5c, top compartment (Freezer concerted to fridge) - -1c.
C. Multiple problems here, ideal temperature of food not getting spoiled is 4c, bottom compartment everything is above 4c (2 hrs food becomes not edible. How can i expect a new fridge to work at this setting if i have set it at 2c intentionally for my fridge.
B. The service engineer says 1-11c is acceptable, how on earth will any customer accept 11c when setting is at 2.
C. Along with the same engineer i checked my 15 year old whirlpool and temp was 1.8c, on asked with him why is this the case, he said that a full time compressor with more electricity, samsung is optimised for electricity and hence it will be like this, why on earth will i care for electricity when fridge cant operate at sub 4c and i have paid 60k for it and food gets spoiled.
D. He again rudely brushed through saying inverter fridge is like this only and unless its above 11 there is nothing to fix, 11c? Thats not a refrigerator
E. He had called his office and they directed him to do couple of more test too which he conveniently ignored and left saying she to samsung this is false claim.
All my food is getting spoiled and i need an immediately resolution on this. Link for ideal temperature for food to not be spoiled: http://www.vegetableexpert.co.uk/refrigerationandcoldstorage.html#:~:text=the%20...⇄ too%20low%2c%20vegetables%20can%20freeze.

I am really fed up with samsung, its product and service. They start with assumption that customer is lying, no one will if everything is working fine and i have already paid for it.
