Myntra.com — Order Cancelled without my permission

I ordered 1 Under Armour Women Hoodie Sweat Shirt from Myntra on 30th october, 2020 at the price of Rs 633.00 in sale on Myntra. After that Next day on 31st oct, 2020 order was cancelled by Myntra, they sent me an email your order is cancelled due to technical issue. When I Called Myntra customer care they told me just they will give me only 100 Rs Myntra Credit. But when they told me this the order price increased from Rs 633 to Rs 2924. They didn't give me any equvivalent compensation . They didn't re order my order at the same price of Rs 633. and they didn't give me the actual refund when the order was cancelled by Myntra. They didn't resolve my issue. And after all this they sent me an email confirmation " your myntra order is confirmed and will be deliver by 4th november". They mislead us. We waited till 4th nov and we didn't get my order. When I called myntra again they told me your order is cancelled by technical issue. and we can do nothing except myntra Rs 100 Credit thats not reasonable for me. And they told we didn't sent you email but they done that. After that they told us we will contact you in 48 hours what we could for just only email. They din't contact me or didn't send me an email or any information. They totally mislead me or wasted my time.

I want the refund of actual price of that Under Armour Sweat Shirt order from now.
