DPD tracking shows arrived at hub then nothing!

First time this has ever happened to us. We sent inventory to Amazon twice last week, on 2 different days, to 2 different fulfillment centres and both have been confirmed to have arrived at hub and then nothing. One consignment was sent to MAN1 and one to LCY2. The strange thing is the delivery to LCY2 has checked in and been received in full by Amazon!

I have spoken to DPD about it, they say it is quite common as all FBA packages get loaded on to trunks and make their way to Amazon FCs. Sometimes they do not get scanned but still turn up at Amazon.

Just wanted to know if anyone else has experienced a similar issue with DPD?

Did not take out the extended liability (will not be making that mistake again!)
