Food Panda — status shows delivered but I did not receive any food or any call

Address: Kolkata, West Bengal, 700060

29th sept at 6.25 p. M. I ordered from 'the empress', behala via foodpanda an amount of food rs. 101.92/- (Order code: y8ot-5x2r) and the restaurant confirmed thr order within some time, the status changed to 'chef at work!' and for the next 5 hours the status remained so. I had a lots of chats with support in between but other than their standard templated answer to wait for couple of minutes i received nothing. I even tried to cancel the order but as the 'chef at work!' it's not possible to cancel. And at 11.28 p. M. Suddenly status changed to 'order picked up', 'near you' and 'order delivered'. I didn't have any clue what happened there. I let the support foodpanda support know the situation, the again asked me to wait for couple of minutes while they investigate and after few minutes simply disconnected.
