Amazon India — rude behavior and unresponsive

Website:

Amazon.in

False promise by made by amazon that it will deliver by 18 sep and it did not deliver my product on time. They directly pussed my delivery date to 21st sep when i called them the keep on saying you have to wait till 21at sep nothing can be done for this and representative are very rude they shouting on me instead. They dont feel important to update customer on ther product they just saying your delievry will donr on 21st no efforts to solve customers. Still i am waiting their is no update when will i get the delivery. They even shared wrong tracking number. Very bad experience after paying 24000 i am not getting my product on time and they dont value me atol.
