I never Ever have had any problem and I live overseas.
The only *problem* I could refer is shipping times. But that's not a BIG problem. I always have my packages sent by USPS and then in Argentina, Correo Argentino. never lost anything.
Regarding FEDEX, UPS, you must claim for the signature proof. From time to time I face the same problem at work, but after reaching A HUMAN on the phone, I claim for the signature proof. Everything came to a good end, eventually.
Hope you can solve yr situation soon! :D:D:D:D:D:D:D
