Pathetic customer service , arrogant and lazy staff

I received a parcel notification but misplaced the piece of paper.So today I drive 25km to Schauderville post office in PE. 3 Tellers on duty only 1 is working. No idea where to queue and none of the staff even bother to ask what you are there for. So after standing nearly 10min in the queue another customer says this queue is for licensed. Move to the non-existent queue on the other side stand for another couple of min. till 1 of the other 2 that are loitering says "next customer". I explained that I received a parcel notification but misplaced it can she check the log book or the system for the parcel details. All I get is "no slip, no parcel" so I ask what now and she asks "was it written in red or blue pen" like I care to check what colour pen it is written in. Furthermore, she then asks local or international parcel and I say International parcel. I ask can I not produce my ID and she checks and the simple answer is again "no slip, no parcel". I paid thousands of rands for the goods only to be told "no slip, no parcel" yet you can go to another post office and theres a book with all the parcels that are there with Names and tracking no's. Such pathetic customer service, arrogant and lazy staff. It is festive season roads are busy and then 1 need to deal with *********** staff that are probably paid from my hard earned tax money. Disgusted for days!
