Avoid
First off - do not use this service. Like many other people here I can only agree, they are one of the worst. But then, what would one expect from an chinese owned algorithm running in some cloud to book shipping capacity from real carriers. They don't have any support personal I suspect, e-mails are neither acknowledged nor answered. Their tracking is completely incorrect for the actual item being tracked. The delivery time for an item from Germany to UK was 4 weeks instead of the claimed 4-5 days.
