Unfortunately, once I have shipped your package this issue is out of my hands and now the responsibility of the USPS.
If your package is showing delivered but you never recieved it, please tell your local post office about it and provide them with your packages tracking number. They will be able to help you from there.
Please double check your confirmation email and make sure you put in the correct shipping address.
I am NOT responsible for packages that were lost or misdelivered and addresses that were put in incorrectly.
