Swiggy — refund not credited to bank account after 10th day

Address:

i dont know exactly

I had placed an order of 267 rs on swiggy after half an hour i got a notification to modify the order due to lack of items which i had ordered. So i cancelled them all and placed an order of rs97. And they showed that rs 173 will be refunded. The order was placed on april 1st. Till today, i hadnt received the refund. I also contacted the bank, they told they hadnt received any..
Please help me to get my money back. Even a 10 rs in important to me.
