Myntra.com — Regarding delayed delivery, delay refund

I have ordered a Puma shoes on 5th Nov and delivery date was on 18th Nov but you guys re schedule it to 23rd Nov due to which I had cancelled my order on doorstep delivery but there was no ivr call from Myntra to confirm cancellation and after 4-5 call refund was done on 24th and now that product is out of stock. It was in stock till 22nd Nov. Now it's totally your fault first delay in delivery and then delay in repayment and now item is out of stock. And now you guys are telling that you cannot tell when it will re stock. This is not I'm expecting. I'm disappointed and want some proper solution. I have cooperation but what is the result of cooperation that I cannot buy the product what I want.
