Pathetic Post Office Service

I have been tracking my international parcel online and apparently states there was a missed delivery 25/06/18 and until which is frankly impossible because the delivery address given always has someone available to collect parcels, hence I gave that address so as to not miss a delivery. Since the 25th there has been no delivery attempt.

I have sent three emails to customer services and no response. I called customer care and I waited for over 30 minutes before giving up because I can't sit and wait all day for a consultant.

I previously received my international parcel without any issues but I really don't understand what's taking so long and I urgently need the parcel. It's very frustrating when you do everything you can to contact them and they don't respond.
