[Resolved]  Swiggy — coupon code error

Address:

Mumbai City, Maharashtra, 400033

While placing my order i had applied an coupon code (Swiggy6) which was applied successfully.
The amount was reduced from 322 to rs. 247

However after selecting the payment method, and confirming the order, the amount shown at the end page went up to 322 again.

I talked to a customer agent immediately but he refused to help me, so i cancelled the order soon but still #swiggy charged me rs. 161 for the cancellation.

It was not a mistake from my end, then why would i bear the cancellation charge???

Kindly help.
