Parcel still at JHB INT Mail Centre (HUB)

<p>I have an international tracked parcel that arrived in the country on 20 March. It has been to and from Customs, (the leaving Customs date is listed as 31 March), but now it is listed as still being at the Hub.</p> <p> </p> <p>The last few international parcels I have received have arrived about a week after leaving customs, but this parcel seems to be taking a bit longer?</p> <p> </p> <p>With all the public holidays coming up, I am concerned there will be additional delays.</p> <p> </p> <p>Is there any way, the processing can be expedited? Or can I collect from my parcel from the Hub, where it seems to be "stuck"?</p>
