Firstly please make sure that it has been at-least 24 hours since the tracking information said 'Delivered'.
If it still hasn't arrived either your package has been stolen, you have given the wrong address or the shipping carrier has made a mistake. Unfortunately, we do not offer refunds or free reshipment for these orders. We get a lot of people trying to scam us by telling us the product hasn't arrived when it has. So we do not offer refunds for this reason.
