Sending an item through paxi - Consumer Complaint for PEP STORES

I went to the pep in Katlehong Letsoho shopping Centre the store number is 0996. I was the to send a parcel through paxi, the cashier that was assisting me is Seya she told me to pay for the R89 for the paxi bag . Mind you as she said I must put my staff the ship didn't check only asked what I was sending I told her that I'm sending my mom's clothes to Mthatha she then sealed the plastic and told me that the a lady that's gonna come and assist me . In like 5 minutes or so another cashier came she started yelling and she was like " angeke ngiyenze mina le eseyivaliwe " she then asked whether did Seya opened and checked what's inside the plastic I told her no she didn't I waited near the teller for something like 29 minutes without any help nor communication. I went back to this lady and asked what's the way forward because I'm standing there like a fool they not saying anything to me.i told her everything that was inside the plastic including my mother's medication and that's when she lost it telling me that she won't send that paxi.Little did I know that paxi doesn't send prescribed medication and I told the lady that it's okay I can take out the meds and that's when she told me that I'll have to pay double the price. the lady said " uyabona this is your fault". That's when I took my staff and left the store . I actually don't know how paxi procedure works at pep but I strongly believe that they should first check what you are sending rather than making us pay and they asks later what's inside . I am so disappointed the service was terrible
