Frustrated with poor service

I am really frustrated with the service of PAXI, more specifically with Skynet. A parcel was send on 30 August from PEP Stilbay to a PEP in Witbank using PAXI. The parcel was supposed to be delivered within 7-9 working days (R79.95 package). When the parcel was tracked, the last entry was on the 31st. Saying that the parcel has been picked up by the courier. The entry remained until the 12th despite many calls from me. After phoning them for the umpteenth time on the 12th, PAXI's customer centre said they have located the parcel and it is on it's way. It will be delivered on the 13th or at the latest the 14th. As we received no news, I tracked the parcel again today. The last entry was on the 12th, saying the parcel left the George Hub of Skynet. Nothing new, Contacted PAXI's call centre again. The lady said she was not sure what the problem is. I asked to speak to the manager. She said she will see if she can find one. She then returned saying the manager is on lunch. I am very disappointed. First the package was 'lost' and now it is again for all practical purposes 'lost' as no one can give me any answers. It has now been 11 working days (15 days in total). And there is no indication of where the package is at the moment or when it will be delivered. I am waiting for a response. Please... I must also add that I used the service quite a lot before and were very happy with the service then. BUT, the previous times the parcel arrived in time (as promised) and the tracking was updated, so I knew exactly where the parcel is at any specific moment.
