Amaron — Service issue

Sir with due respect I have purchased a Amaron Flo battery no AEG1331U230257, AAM-FL- 00036B20L on 12.09.2020 but it has been installed/ fitted in my vehicle on 22.09.2020. Sir in my warranty card the salesman has changed the date of purchase at the time of installation i.e. 22.09.2020.
The battery has been dead on 15.03.2023 and I have registered a complaint on 17th march 2023. As per the warranty card, warranty will be expiring on 22.03.23.
Sir I have submitted the battery to Surjit Battery and Auto Parts, Model town for replacement and he sent the battery to company but he said the date has been expired and company refused to replace it.
Sir it is not my fault kindly consider the replacement at the earliest.

Your valuable customer
Dr. Karan Nirankari
