Bad service Pep Home Protea Glen Mall

I got to Pep Home Protea Glen Mall to send my parcel via Paxi it is my first time using their courier service, I got to a lady cashier who did not have a name tag and I showed her the parcels I want to send and I asked her to recommend the size of the plastics I will need then she gave me the plastics and told me to go to the other side of the counter to place the parcels myself in the plastic. And I asked her what should I do next please tell me the whole procedure as it is my first time using your courier then she told me to take out my identity document, the receivers address and telephone number and wait to be called so they can scan the parcel. Then I put the parcel in the plastic and sealed it and they called me to come so they can scan my parcel only to find out that u was not supposed to close the plastic then the other cashier asked her if she told me not to close the plastic and she said no she didn't tell me. Then came another lady by the name of Thusang she started arguing with me and di3give me a chance to explain my story to her she was so rude and did not show any customer service to me she took my parcel and put it aside and left me there to help other people and came back later to argue with me more saying I must fix the mistake I did myself if I can't fix it I will have to buy another plastic. I was tired of arguing with her and I told her to please assume as I am late for my appointment already and she kept going on and on while helping me. I got the worsed service ever at Pep Home
