Not receiving parcel no explanation unprofessional

WAM25935 is my parcel number i got a message on Monday 31 August 2026 they will deliver my parcel, the same day late in the afternoon i received a message stated they couldn't deliver, with unknown reason, no phone call from the courier. There was people at home waiting tge whole day for the parcel no driver was there to deliver. I've send an email regarding the situation the same day asking what happened and where is my parcel. Someone from Durban office phone and said they will sort it out with Moreesburg office and Moreesburg office will phone me up untill today no phone call no communication nothing no parcel. Today 2 September i phoned head office asking what happened first she couldn't fine the parcel number I've given her then she found it, then asking to confirm my details, then she said the will deliver today saying she logged it so, now im checking my parcel is still sitting at the depot in Moreesburg, still no phone call from them still no explanation still no parcel this is top tier unprofessional and really making me not trust anything to be courier by this company
