IndiaCakes.com — India cakes didn't process my refund from the last 2 month and the customer service guy disconnects the call

I had placed a cake order for Alipurduar on 7th Dec 2021 worth 450/- and once the order was placed within few minutes India cakes came back with an email asking for additional 500/- which is apparently the delivery charge failing which they wouldn't be delivering the order and they didn't. Had I been aware that the delivery charge is more than the cakes price I would have never placed the order in the first place. Its been 2 months they haven't processed any refund. Today 3rd Feb 2022 I called them to which 4 consecutive delivery executive disconnected the call after listening to my problem and once of them misbehaved with me and replied that they are a big company and have too many orders so refund might have been overlooked. Also they don't refund rather they add it to the wallet which you can use for subsequent purchase. They are big time thieves who charge money once u have placed the order failing which your money is gone down the drain
