Myntra - Myntra wasted my time and scammed me They didnt

I ordered a product From myntra on **th of june and they said they will deliver it by **th of june , They failed to deliver it by that time So I called customer care ( For which I have audio proof) And I said them about my issue and they said me that we will loo into it and get back in **hrs, I also saw that the product price has suddenly increased as I purchased in sale event so I waited till **th of july when finally I got a text saying sorry due to internal issue you produt got cancelled and we will give you refund, They made me wait for ** days and cancelled the order without asking me and also the price is hiked now, Hence MY time is wasted my money will again be wasted to buy the product for hiked price and myntra just walks home with a sorry.

So, I would like to file a complain as I heard you guys really help, because this is a violation of right and missuse of consumer's time
