Amaron — Amaron Amar Raja Battery

I had purchased Amaron Amar Raja 2 wheeler battery for my bike on 09/01/2023. While purchasing I was told that the battery is protected by 2 years of warranty, which means it will be replaced by the company if it fails to work within 2 years of date of purchase. The battery stopped working since end of October this year. So I went to garage and told him about it. At first he started refusing saying that the company says 2 years while selling but doesn't replaces the battery after 18 months. And at first told me to contact the company on my own and get a replacement but after a lot of arguments he took my battery on 05/11/2024 and said he will send to the company for replacement. And told me to be back by 12/12/2024 for the new one. After wasting several he gave me back the same old battery saying that the company didn't replace the battery instead they have given the same old one back. So if you want a new one, you need to buy it. So, how is 2 years of warranty equal to 18 months only ? How is it not 24 months ? And if that is the case then why during sale the garage and the company says 2 years of replacement ? Now since only few days are left I cannot even go to the company directly. How is this not fraudulent advertisement ? I m attaching the photo I took of the warranty card while I gave the card and the battery to the garage owner. The date can be clearly seen on it.
