Myntra.com — amount deducted but order not placed for lafille navy blue solid set of 2 shoulder bag

I placed an order dated 21 dec 2019 for lafille
Navy blue solid set of 2 shoulder bag. The amount of rs 584.10 was deducted from my bank but order not placed.
Either i want my order to be placed or get refund of my amount.
This is not how myntra should treat customers. I placed an order for the very first time and i am disappointed. I am scared if i will get the refund back.
Trusting an online site is difficult these days.
