Amara Raja — Battery Life

Summary :I bought Amara Raja battery - AMARON AP-BTX5L 5 Ah Battery for Bike. This had 4 year warranty and has not even come for 4 months .I feel cheated when reputed companies cheat honest customers
Background : The battery was ordered on 20 November 2020, Order#[protected] and delivered on 29 November .Since last few days it has not been working

Suggested Option :As i didnt buy locally, i need to know how to get replacement at home or full reimbursement Plus compensation for my time wasted
