Website:	Amazon.in

On last thursday i. E. 28. March.2019 i placed an order from amzon.in worth rs 26999. Order details
Order #[protected]
Placed on thursday, march 28, 2019.

It has already reached my location and they don't want to deliver it to me!! They said they did not receive money from me "but ofcourse they received it". Ofcourse amazon.in received my payment and send me a confirmation email and sms messages, and they despatched my order on the same day. I have received a payment confirmation from sbi also. I do not know why they want to deliver it to me. Next week is my grandmother's birthday and i need to use it on the same day that's why i place an order.
I have contacted amazon courier manager and he said "we didn't receive your money and his behavior is too rude" and when i told him the amaz have received the money and he replied "we are going to refund your money".
*why would they refund my money without my agreement while it has also reached my location?? I would have no camera on my grandma's birthday!! I trusted them and ordered from them. Please help me
