Late and bad service

Good day <br> <br> Early during this Month I sent documents from PostNet in Medowridge in Cape Town on the Friday it was suppose to be sent out however due to the driver not arriving on time the document was sent the Monday and arrived the Tuesday at its destination. The post office assured us it was received the Monday however later discovered they checked the system wrong and only received the Tuesday. When returning it was said that a bird flew into the plain and it did not arrive on the day, the situation was resolved. At the end of last week a document was requested to be sent from Pretoria to Pretoria and back to Cape Town. Due to the fact that I am in South Korea and hope to start employment soon my employment is withheld due to documents not being submitted sooner. The courier service in Pretoria received payment Monday, there system was down and it was sent Tuesday, it should have been received Wednesday however it is stuck in Cape Town. This is totally unacceptable, I constantly need to Skype my parents who are over 66 to sort **** out and I have no access to communicate the branch, where the documents should have arrived Friday delayed once again prolonged, UNACCEPTABLE
