Amazon India — wrong product sent to me and they are refusing to accept.

I had ordered a huawei watch gt2 in amazon.in but they have sent me a cheap quality watch.
I had complained them but they are refusing to accept it, telling me that they will not refund the value of the product.
The value of the watch was rs.17449, but they had sent me a different watch.
Please take some action, as the value 17449 means a lot to me.
