Myntra.com — product not delivered and they cancelled the order without telling me

Address:

Hyderabad, Andhra Pradesh, 500084

I ordered one top, it was showing in stock when i ordered it. Later on i got message from them saying "your product is delayed but it will be delivered". Today i checked my account on myntra and they just cancelled my order without even telling me. Now solution they are giving is to order it again, which i cannot do because the product is out of stock now.
