Street Style Store — Won't be able to receive order

I am unable to cancel my order just because it's shipped? What if I want another color or change one item with another? you deliver late at one point I can deal with that but why can't I cancel my order? I don't want you to work hard when I won't be able to be there to receive it. This is such an inconvenience to us.

order id: #8055112
please cancel my order I won't be there to receive it.
