If you are waiting for it to be DELIVERED to you, .... you will wait for a LONG time. The delivery man on;y knows a few streets, has a push bike with two flat tires & only gets his mail for delivery every day the postmaster is in a good mood or been paid!!!
Mail from England gets into our PO Box (apartado) within 7 - 10 days of being posted in England - & THAT is coming via Sto. Dgo. sorting office!!! We have had mail in 4 days! It takes longer from USA or Canada, but of course that is not the Dom. Rep. poastal services fault!!
Try going down to the sorting office nearest you, talk sweetly to the man/woman in charge (Smiling a LOT & praising them on 'hair-do', smiling eyes or something. Offer to help sort through the mail because you know what the package will look like ..... And ASK FOR THEIR HELP!!! It is amazing how they will bend over backwards to try to HELP someone!! Good Luck - Grahame.
