WORST POSTNET SERVICE EVER (ILLOVO SANDTON BRANCH)!!!!!!!

So i posted my mothers present on the 23rd July 2018 and requested an overnight courier from Johannesburg to Lusikisiki. I follow up Tuesday afternoon and was informed hence the destination is a remote area they don't do an overnight courier but they only service the area on Mondays and Thursday (when i was at the branch no one told me this). Fine i wait for Thursday and track the parcel online and realize that status says data received so i call again to ask where this parcel is and i was informed that they will deliver after 12 noon. Today Friday i follow up again as my mother haven't received her parcel yet and im informed that the courier company doesn't go to ''that remote area'' and that my mother has to liaise with the courier company and meet in town!!!! What nonsense is that???? What did i pay for????? i asked them who did they tell yesterday that they cant deliver as i did not receive a call from them!!! Now im informed my mother will receive her parcel Monday( THE 30TH JULY) next week !!!!!! But my mother has to go to town. i freaken paid R570 for this parcel!!!!!! What did i pay for when all i asked for is not done.. THIS SERVICE IS REALLY POOR AND UNCALLED FOR!!!!!
