Zomato — I haven't got the refund for three of my orders dating back to july 2019

Address:

Chennai, Tamil Nadu, 600073

I haven’t received the refund for three orders which got cancelled from zomato’s end as the delivery person wasn’t available at that time. I was told that the refund has been initiated for the three orders and i was even given a rrn number, but my bank has clearly told me that the rrn number has no refunds against it and they haven’t got any money from zomato yet. I got back to zomato through mail about this twice, their response is irresponsible, vague and the same every time. They always tell me that i have sent the rrn, which actually doesn’t mean anything if the bank tells me that they haven’t got the money.
