Royaloak Furniture — product cancellation

I ordered a wadrobe and a shoerack from royaloak online on 9th may (Roy0033627). There was a lightening delivery deal going on. I got the shoe rack but the wadrobe didn't arrive. The eta was 12th may and installation on 14th may. Not only did they delayed the delivery but later stopped picking calls.
Wrote emails and tried calling multiple times.
Called a representative to cancel the order, he promised to send a cancellation mail and refund confirmation, but no response yet.
The wadrobe was for our new house, and we had no option but to buy a new one from elsewhere.
No emails, calls from royaloak for refund or cancellation yet.
