The first thing you'll have to do is to think hard on why you'd like to cancel the order. If you really want to, then, contact customer service: support@guitarzoom.com (phone support also available). The team will check with shipping if your course has already shipped. It's highly possible your course has shipped out already, as courses are shipped before the end of business day.

If not, then they can go ahead and refund your order. If it has shipped, then you would need to refuse the package so it will get returned to us, and they can issue you a refund then.
