Zomato — Order [protected] not delivered

Placed the order for ice cream and after waiting for 1 hour, Order# [protected] is not delivered to me but was marked delivered. I tried calling the delivery executive that entered my apartment and he says he has delivered at some other house. I kept calling him to deliver to me, but he said I’m busy now with other orders and will check after completing those orders. He came back after 4 hours and asked ke to take the ice cream which has been kept outside for almost 5 hrs now. There was no point in accepting that ice cream as it wouldn’t have been edible after 5 hours and requested forna refund. as usual there is no support available over chat and I had to mail zomato. Following up since 7 days but they don’t even bothered for a reply and no resolution.
