Incorrect courier address on waybill as given

Appalling service, I have sent a co-worker with a parcel to send to Durban from Pretoria PostNet Station Square, with a typed and printed address pasted onto the parcel and my co-worker comes back with a waybill having an extra line on the address erroneously included which could easily mean the parcel might not or most definitely not get to the location it is supposed to be delivered. I had phoned and spoke to Kgalaletso asking her to rectify the address and e-mail me the correct waybill and was told her colleague made the mistake and she will just scratch the extra line off on the waybill print out. Talking of a ridiculous service, meaning the address will still be wrong on their system should the waybill get lost. Speechless!!
