If you don't get your package you…
If you don't get your package you should call your bank if you used your debit card directly. If you used a credit card call them they will look into it and refund your money often they refund you and then they try to recover their money. If you used PayPal (which you always should) they will also return your money. Now this is if you never got your package, be safe and use PayPal they are easy to work with, or make sure your credit cards have fraud protection, your bank should always help you unless you keep doing it then they'll think you're the fraudulent person.
