I arranged a trade with another person through a forum who lives in Belgium (I live in the US). It took four months until my package finally arrived from her...and she has yet to receive mine! I contacted USPS and they said that it is probably stuck in Belgian customs and that there is nothing I can do but wait and hope it arrives. I shipped it Global Priority Mail and they said unfortunately they cannot track it at all, even though I have a receipt of purchase that includes that customs form number and label number. So what do I do now? I know I got mine after four months, so there is still a possibility that she'll get hers, but how long should I make her wait? And if it doesn't come, do I send her stuff back?
