Once the package has been marked as delivered by the courier but is not actually received, please try checking with the neighbors to see if the package was mistakenly delivered to them. If you are living in an apartment, check if your establishment has a storage or mail room where the package may have been kept instead of being taken straight to your unit. If you suspect that your package was stolen, please contact your courier immediately to file a lost package claim. As with any case of theft, you should also file a police report. While they may not be able to retrieve the package without any witnesses, it can help prevent the same incident from happening. This will also help as additional evidence for your claim with the courier.  We will provide any appropriate document to help with filing the stolen package claim with your courier.
