Samsung — Being forced to pay for repair again and again for faulty galaxy A71 device

Dear Sir/Ma'am,
Have purchased Galaxy A71 phone from Samsung Shop portal in October 2020 (invoice attached), being old loyal Samsung customer and already using many samsung products, I trusted the brand and get ahead with this purchase. I am really sorry to say that this purchase has turn out to be a nightmare in past One and Half years.
-The Device first brokedown after 10-11 months in September 2021, where it was not switching on one day and your service center repaired it free of cost as it was under warranty.

-Right after 3-4 months its display become dead for reason not known and I had to pay INR 6000 to your service center for the replacement (Neither the phone was ever dropped or mishandled nor damaged by water etc). The e-mails with receipts and service center job sheet enclosed for your reference.

-Now right after few months of replacement of screen, once again the screen become faulty and half of the Touch is unresponsive. Again your service center demanding another INR 6000 approx for screen and touch replacement.

This is never expected from company like Samsung, how many times shall I invest in the repair of such a pathetic device just because it is out of warranty. I am not a rich person and can neither afford hefty repair charges after every few months nor can I afford buying new phone every Year.

The phone is in mint condition without any scratch or sign of damage it is the display and touch which is getting faulty number of times in just a span of 18 months.

Thus I have requested them to either get my phone repaired and guarantee that same flaw would not happen again, without any charges or simply refund my hard earned Money. BUT THEY ARE DENYING THE SAME. Warranty or no warranty reputed company like Samsung should not sell substandard products to their loyal customers.

Request you to please help me to get out this trauma as early as possible as I am left without working phone, which is a necessity in todays time.

Awaiting your positive response.
Thanks
