paxi parcell still lost

i requested my parcel to be sent from pep store at bushbuckridge, ive given the person my nearest pep address here in pretoria woodlands. the cashier captured and sent my parcel to Groblersdaal (5859) so i disputed same time when i saw the sms i quickly told the person who was sending the parcel that they processed to a wrong address, and the person went back to pep and tell them they sent to a wrong address, and they told her that's where the code 0081. and they gave her the WhatsApp number to re root the parcel to a correct address. she did as they told her but still it did not come to my address. so my question is why the cashier did not confirm with the sender if is the correct place before sending. because the sender knows i am here in Pretoria. now i am asked to pay another R70 to send the parcel to pretoria not groblersdaal.
