Service is slacking an Staff are pathetic!

My package was supposed to be delivered at on the 16th latest at Mthatha. Tracking (which was more helpful than their pathetic staff) shows that the parcel was received in JHB on the 14/07/2015 and has arrived in East london on the 15/07/2015. To enquire I phone the head office they told me to phone the east london branch. I phone the East london branch they told me to phone mthatha delivery guy \Walile on ***". I tried phoning this guy and it goes to voicemail. By now I have lost my patience and phoned JHB head office to speak to the operations manager (called Peter). Well he attended his phone twice but could not hear me and I could hear him. All I heard was him swearing cause he could not hear me. How professional!!"""
