Myntra.com — Cancellation of order and 5 times price hike

Address:

Embassy Tech Village, Outer Ring Road, Devarabeesanahalli Village, Varthur Hobli, Bengaluru

I have placed an order for a product (Safari trolley bag for Rs2249) on Myntra on 20th December 2021, it was expected to arrive on 4th Jan 2022, although it was a long time period but I ordered. The products was in the offer and I also applied a coupon. The order was placed successfully. On 27th December a message came that your order was cancelled, when I checked it states ' order was cancelled due to your request' even when I didn't cancelled that. I called customer care for this issue and they replied it cancelled from their side. So I told them about out of stock and price hike about 5 times but they didn't provide any solution. They asked me to order at that price (hiked price).
It was okay if there was some increase in the price. But the price went form around 2200 to 9500. There was no problem from my side so why should I pay that much.
If Myntra wanted to sell that product at the higher price then why showed a lower price and then cancelled it.
