Generally, no obligation is in place if no payment has been fully executed and received, so there should not be any problem in cancelling and order in progress.
In case you already made a payment, we won’t be able to cancel your order and refund you due to the nature of our business. In any case, we advise you to check with our sales department to explain the situation and see how things can get settled for the best. We always try to find a solution.
