Flipkart — Sleepyhead Flip-Dual sided 6 inch king high density foam Mattress

Dear customer care representative,
Order ID OD[protected] placed on 8th Nov 2020 and was cancelled by seller due out of stock but actually you can see same items are available with different Prices on Flipkart as well as Amazon. This was purchase of amount Rs5967/-due marriage of my younger sister. Now the same item is available on Flipkart as well as Amazon of amount Rs7739/- . If the item was out of stock why item was booked on Flipkart platform and due COVID everybody running out of money, I don’t have money to place new order with high price as my money is stuck between you and bank as Money transfer for same order on 8th Nov and it will be creates again on same accounts on 24th Nov and money is stuck. If the item is out of stock then why seller is selling on same platform with high price.
Please deliver the same item with price on mentioned address.
Thanks
