Hello I had a sale and I had it set for calculate Shipping and it didn't give her the option, It showed free on the listing so when the customer bought it she didn't pay shipping. Now she doesn't want to pay the extra shipping. I need to cancel the order and don't know how. I found out that calculating the shipping is only available to US and not Canada. Why isn't it available to me in Canada? And how do I cancel basically my only sale!
