Anyone having problems reciving things from abroad

I ordered a DVD from Hong Kong, a PS1 game from US, and a graphics card from Hong Kong on the 24th May, none have turned up, despite all sellers having good Ebay feedback.

Its only my current address, I reckon post office is stealing mail, as postie never knocks, puts card through door pretending he rang buzzer(I have been awake each time he has come round)

Even a XBOX360 game sent around same time from UK though went missing, as did a bank card addressed to me, and a pin number, and a postal order.

Essentially anything of value which is sent non trackable goes missing, everything sent tracked arrives, so im suspicious.
