Myntra.com — cancellation done without asking me

First i order jaipur kurthi (Order no.:[protected]-8588101). It didn't received on the date said. Then a message came as sorry for the inconvenience and it will be delivered in another date. It didn't came and when i checked my mails now, i got a mail on september 20, saying that it got canceled. I ordered that item on september 7. They didn't even called me once in the number which i provided.
Next i order buckle up (Ladies belt) of order no.:[protected]-8705203 and i ordered it on september 21, because i didn't check my mails for some days, else i wouldn't have ordered. Same is the response i got, it also got canceled. Can i get a response this time or i should call and complaint again.. Thank you.
