Swiggy — discount coupon didn't work

Address:

Chennai, Tamil Nadu, 600119

Today i have ordered food from swiggy by applying 50% off coupon 'swiggy it'. Before applying coupon the order amount was 242/- and after applying coupon the order amount shown was 123/- i selected the coupon and proceeded to payment via google pay. But then after making payment, 242/- got debited from bank amount which i didn't notice at first. Noticed only after checking the transaction message which i received through text message after the payment was done. While i took this issue to swiggy chat section, the executive was not supportive. I had to uninstall the swiggy app after that conversation with that executive due to poor response and support from their end. So, reaching out to consumercomplaints. Expecting a positive response at the earliest.
