Theft and attitude from Chris at Howard centre, she acts like she might be the manager

I went to Howard Centre in Cape Town to send a package , as I don’t know the sizes I ask the lady at the till to provide the right package size and unfortunately she provided a smaller size as she is new to the job and who I assume is the manager who was not even wearing her uniform or a badge (found out her name is Chris) says I made a hole in the package and not to come to the store not knowing what what size I want. Then she takes my receipt and plastic. Now I don’t have my funds and I had to go ask the new lady to please give me my things so I can have proof that I paid . This Chris lady (she was wearing an orange dress) then gives me a disgusting look. So money has been ****** from me by pep stores at Howard Centre
