Zomato — Asked us to cancel without refund or pay extra money

Hi there,
I recently made a zomato order few hrs back with zomato order id [protected]. After 15mins of order i got call from valvet and he asked us we would need to either cancel the order or pay him extra as the distance is longer than the range. I didn't make any change in my locatiom before/ after order. He told if i cancel order, i won't be refunded. So had no other option other than paying him extra amount for distance. Nothing such is mentioned in app, the support is trash. They don't have any chat/call.
