Boat — mistake made by boat, why should i lose money

I Ordered a Boat Rockerz 550 Headphone from official boat website on 12/Feb/2023 (Order No:[protected] worth ₹1684.15 (Online payment), then I saw some negative reviews about that product and decided to cancel the order, but cancel option was not there.

On 14/Feb/2023 I got call from Boat delivery agent, I said him to cancel the order, But he said this order is already prepaid, I can't cancel it.If it was COD i can cancel it.In the case of Prepaid costumer should take the package and put it to return.

As he said I took the pakage and called the customer care they said we don't give refund after delivery.You should cancel the order before the delivery by delivery agent, Now you have option only to replace the Item.
(As I mentioned above "I saw some some negative reviews" This happened with me also, The right side speaker of the headphone is shaking and Noise is comming.)
Then I put the package for replacement on 15/Feb/2023.

Then a new replaced order (Order ID:-4162348EX1) arrived.An delivery agent from boat called me, I said cancel the order, he said the same dailog which was said at the time of first delivery.I said him all the story, Then he took an OTP from me and he cancelled the order.Then RTO(Return to origin) initiated.

Then I called boat customer care and asked for refund they said this is replacement order, You can't get refund for replacement orders.You should cancel the order at first time delivery, But now you don't get refund.
I said I tried to cancel the order at first time only.But your delivery agent gave me wrong information. customer care executive (i think her name is Neha Sharma) accepting that mistake made by them.She is asking sorry.But not agree to give the Refund.

After the fight in the phone call she gave me fake promise as wait for 48 hours i will try to give the Refund.(I have the call recording).But now 53 Hours completed, No any updates

An new package replacement order re shipment (Order ID:-4162348EX1RS1) is arriving tomorrow (20/Feb/2023).But I will cancel this also.

I request Boat to initiate the refund of ₹1684.15 to my original payment method as soon as possible.

I suggestions to people who want to purchase products from Boat website.Please don't do that.Please order from Amazon or other trusted platforms.Boat Customer services are not good.
Thankyou
