We ordered food from a restaurant named shudh, and the bill came to be rs 1750/- and we paid amount itself online but once the order was placed and 30mins later we got a call from a executive saying we have to pay cash on delivery where we already paid online and he is saying our amount would be refunded in 3-4 days. Where we wanted amount instantly to order at other point the executive says like we dnt hv tie up with citi bank and we paid through icici bank. I don't know but too worst experience. This executive is very horrible that he cut down the phone without any explaination.
