Query: Happy - Trance Mellow ; Sold by: Bookbrothers1

I would like to cancel my purchasing from Bookbrothers1 because I did some mistake. But Bookbrothers1 didn't give me that chance to cancel. While some items I bought from Amazon in the same time, I could cancel it without any problem. That was my experience with Bookbrothers1.
