Just Bake — product not delivered. no response from customer care

I had a most disgusting experience with just bake, when they denied to deliver the themed cake on my daughter's birthday. The order was placed much in advance and the payment was made right then. I did not receive any call from them and finally on the day of delivery (Scheduled for 3 - 5 pm), i received a call from them at 3 pm that they cannot deliver the cake. Instead they can arrange a normal 1 kg cake and the call was disconnected. I called up their customer care and my call got disconnected more than 20 times. I later tried connecting them on whatsapp, but still failed to get the themed cake for my daughter's birthday. This lasted till 7 pm and finally the cake never got delivered. With no option at hand, i asked for refund.
