Zomato — I ordered once and paid thrice

Address:

Grace ladies hostel,vayalur road, puthur, trichy, 620001

I ordered a shawarma in an hotel and in the payment option i selected google pay. The amount showed 90 and selected option pay in gpay..it showed transaction failed and i clicked upon retry option in gpay.again it resulted as transaction failed . so after 5 mins i ordered it with cash on delivery. Then after few mins the amount rs 90 was debited from my account twice and it placed as two orders. they refused to cancel the order.if so they cancel they refused to refund it.now i am getting three orders and the customer care says it was my mistake.!
