My tracking number shows that my package was deliver to an individual, since June 25/ 2021 we are in July 5th I still don't know, who has my package. The carrier who supposedly deliver the package gives my documents and my money order to someone without a name and signature? I went to two postal office to report the issue, no body really help to figure out what really happens with my PACKAGE. The worst part my tracking number stop working when I am figuring out myself to whom my package supposedly deliver. TERRIBLE SERVICE , TERRIBLE.
