IndiaCakes.com — Payment taken cake not delivered and no refund given

I placed order for a cake worth 476.51 on 3rd April after their support executive confirmed that they deliver at my location send there is no extra deliver charge. I made payment online and after getting the money, they started asking for 400 rupees more as delivery charge. I refused and they did not deliver the cake nor refund my money even when I asked them on that very moment to cancel my order. Now they don't pick up phone or abuses over phone and disconnects. No refund given yet.
