Future advice: if you want meaningful support, don't purchase any labels via packlink because their support is basically useless.
When you purchase a DPD label via packlink then DPD refuse to talk to you - if you phone them up then after entering the tracking number the automated voice tells you "that's a packlink one, f*** o***" and hang up (well not exactly those words, but close).
If you do need to contact packlink then you will find the details you need in the eBay order details. Though do bear in mind their support response is likely to be slow and/or useless.
In practicality, the item is either going to get sorted out by DPD, or the tracking will never update and you will need to submit a loss claim to packlink - hopefully the item was worth less than the limited insurance they provide and your item isn't an excluded category.
I am not convinced that a service like packlink is fit for purpose for consumers: consumers expect access to a reasonable level of customer support when there are problems and to only be sold services appropriate for their needs. Given packlink have low compensation and lots of items excluded from compensation I am not sure their services are appropriate for retail customers (for businesses fine, a business can negotaiate a specific contract and self-insure if required).
