Ajio — Placed Order and paid money. Order not delivered

I ordered a jacket worth 7.3K from Ajio on 17th july. Paid using credit card. Order is not delivered and i got message that your order has been cancelled, but nothing was updated on the app. Customer service is worst and they don't help I've no idea how to get my money or order. It says order shipped but it's not. I asked the delivery company and they say there's no such order.
