Flipkart — Order Cancellation & Gift Voucher

I placed an order for iPhone 12 129 GB for 60028 on 9th July 22 and right after the payment, the order was put on hold despite of payment Being successful. Upon contacting Flipkart I was told to wait for 24 hours and was assured the order will be delivered as per promised date. But as soon as 24 hours completed, Flipkart cancelled the order to asked me to wait for 7 days to receive my refund. Flipkart did not share any reason for cancellation and got my money stuck for 5 days. When I received the refund, I tried to place an order again but this time, Flipkart increased the price of same product to 65499, almost 5500 more than the original amount. Flipkart is neither helping me to provide the phone at the same price nor they are going to issue a coupon for difference amount. Additionally, I had purchased Flipkart gift voucher worth rupees 30000 for instant checkout but now they are not cancelling them either. Now I have got my 30000 stuck with their wallet and they are not refunding the money for gift card.
