IndiaCakes.com — Ordering transparency and Refund

I ordered a cake from India cakes worth INR 540 and with coupon, paid Rs. 494.
At the time of ordering, there was no mention of delivery charges.
Right before delivery time, i receive an email from Indiacakes (*******@indiacakes.co.in) saying that i need to pay Rs. 250 for delivery charges since the location is far.

I replied that since it was not mentioned before, either they should deliver without delivery charges or give full refund. No reply received from them so far. Upon calling on their customer care, they inform they would give me some Coupon for future usage on India cakes.
Mine is not the only case. My order id is 609297. By mistake, my wife also placed an order on same date with India cakes: 609289. She also received an email saying Rs. 100 to be paid extra for delivery charge. That too for same address on which i wanted the delivery!

With such pathetic non-transparent service, who would like to order back?

Since then, am waiting to hear back or get my refund.
