Rude Cashier - Consumer Complaint for PostNet SA

I was at Kuruman Postnet to pick up a package the lady that was helping me was very rude and the owner of this particular postnet was their and she did not see anything wrong how this lady was treating me, their is two leaflets that I was to sing and she just put it on the counter as she is walking away to get the package she is telling me to sign and put my ID number on the leaflets as far as I am concerned she must stand at the counter and tell me where to sing and put my ID number. I then told her she is very rude ill not resign the leaflets as I signed on the wrong space and she refused to give my package to me the owner come not apologizing or anything and told me not asking me sign or they will not give my package. I am disgusted by the customer service of Kuruman POSTNET.
