Indiacakes.com - Order number Ordered a Cake but it was not deliver and they cancelled the order saying no Refund

I have placed a cake order with indiackes.com on **th for delivery on **th May **** and even paid extra amount of ***/- as they said delivery area is far from their center.
I have even asked four time on chart support on **th from morning to evening. ( reply was it will be delivered)
the fourth time in the evening at * pm when i asked the status of my order they said it will be delivered by *pm but it was not.
When ever i reach to them for my refund they do not respond on the charts and when i reach them on phone ********** they are saying our delivery partner father has expired so we could not able to delivery the order and we will be giving a coupon code and your order is cancelled when i asked for my refund they are saying ( we do not give any refund of the money we only give coupon code valid for a year if you want to use, use it or leave it but we will not give any refund and disconnects the call (twice they have disconnected the call and the executive name is Sonal) She was very unpollutable to the customers and no intention in solving the problem or responsible to give a proper reply. disconnects the call in the middle.

I even tried to reach them on their chart support executive name Sunita talk to her twice no response and another one Ashish he just simply replied not money refund only the coupon code and after that no reply to the message. ( Attaching the screen shot of the conversations and the emails which received)

They do not have any delivery center for which the order was placed and they have never attempted to give a proper reply about the order status when asked.
When status was asked after the delivery date they are giving a sentiment reason that our delivery partner father has expired (If it is true i am sorry for him) and his shop was closed on **th and on that day i have asked them four times about the status they were saying it will be delivered today only.
But when there is no attempt or any thing happened with my order and they them self have cancelled the order.

I said to them i am not happy with your service and I don't want to place any more order with your in future and asked for my money back.
when asked for refund saying will give coupon code if you want to use, use it or leave it and disconnect the call and no response on chart when asked for refund.

I am happy if my money can be donated to who in need like orphans house or covid camp i am more than happy but i do not want my money with these fraud company.
