Unclear/ False Advertising

<p>I've been using postnet for a very long time and the R99 special. From my knowledge ANY parcel under 5kg is R99 to any Postnet. </p> <p> </p> <p>So this morning I went to a branch with a blanket to send it to another Postnet, I did not have a box so I asked the Lady for a box. She gave me one and all was good until she told me I must pay in because it exceeds the weight. </p> <p> </p> <p>I disagreed and said I weighed it at home and its maksimum 4kg. She agreed that the parcel is less than 5kg. She then told me I'm paying extra for Volumetric and showed me to the poster which caused more confusion because it says 15kg max volumetric. </p> <p> </p> <p>It started a disagreement and I ended up refusing to speak to her as she was getting very arugant. So the owner tried to explain Volumetric to me like a school child which was irrelevant because my question was "Why must I pay more when I am within the 2 limits of less than 5kg and less than 15 volumetric kg". </p> <p> </p> <p>It ended in a huge argument and I left. As I went onto your website it states clearly "All just R99 for your first KG!!!", NOT FIRST 5 VOLUMETRIC KG!!!</p>
