I usually get my packages within a week. That is until my last package of gp4ks which took a week and a half because they used a supply depot in Belgium as opposed to the UK. Never had a lost package.
Knowing international shipping as PBK does, they usually have a set protocol as any company who has a lot of international orders does. They know there are delays that are out of their hands and that's why they always wait past their estimated period for your order to arrive before taking action/ giving your case priority.
If you're angry you should be at the USPS (who handles all of PBK's packages in the US) who's in a money rut and has most recently cut back on people and depots.
I expect my $30 pro4's too.
