Ajio — Not helping me in changing the delivery address

Hi,
I am Ayaan. Ajio customer care is always taking their customers for granted. I recently placed a new order on ajio. Which is not been packed and shipped yet. I somehow chose the wrong delivery address from saved addresses. I contacted the customer care many times but they are not willing to help me. They are saying to cancel the order. But the prices are doubled up now. They can easily change the address. They behave rudely and said not call them for this issue again.
ORDER ID #FN[protected].
I have also shared them the new address and all details on the customer email id. But giving excuses only.
Please help me out.
