Foodpanda — unsatisfactory customer service which lead me to lose my meal and money

Address: Chennai, Tamil Nadu, 600029

Website: Foodpanda

Today i've ordered food through foodpanda and made my online payment.in meanwhile i thought to add an item into my order and contacted them. When i'm speaking to them my order got cancelled. I've asked the same nd got reply as due to some technical issue. And they also replied me as they will be giving a refund.
Ive replied like i dont want my refund as it takes 7-10 working days. Ive asked them to reorder. But they didnt resolve my issue and kept on insisting to take a refund. And now i lost my money for minimum 7 days.
