Samsung — Defected product- International Warranty

Hello,
I had purchased a Galaxy S21+ from a local dealer in the UAE a month ago. Brought it to India, and after a couple of days o[censored]se I found that the top speaker unit has distortion in it, and this is not expected from a phone of this range. I contacted the customer desk of Samsung India and they refused to accept under the defected catergory and stated that it my phone is not liable to replacement by Samsung India. In this condition of the pandemic, overseas travel is impossible and Samsung refused to replace or at least repair a defected product, stating that it is not covered under warranty in India. This is so unfair and poor from a company as huge as Samsung. And what's more, just a few days ago I noticed the green tint issue on grey backgrounds under very dim light, again not ti be expected from a 1000 USD phone. These repairs will cost as much as 20 percent of the phone's price itself. This must be remediated at any cost. A sealed product having these many defects is really unacceptable. And Samsung has to help me with a replacement product.
