IndiaCakes.com — Cancellation of order

I placed an order from IndiaCakes.com. they placed order. but after 1:30 hour they send a link to pay another 250 by saying location is far from them. I asked them to refund but they are saying they will give only coupon code but i want refund against original payment method.I don't want an IndiaCakes coupon. There is no turning back to IndiaCakes.

Regarding this i tried to reach customer service via call, chat and email are non responsive & unethical behavior.

Refund my money back
