PEP Delmas

I went to pick up my PAXI parcel at PEP Willowbrook Square in Delmas Mpumalanga yesterday. However I was yelled at by a cashier saying that they are very busy with customers and that I have to wait until they are done helping the customers that are waiting to pay. (the store was packed with customers and the queue very long) I am on crutches after knee replacement surgery and cannot stand for long periods. They two cashiers called customers from behind me to come pass me to pay their items, making me wait. When I asked when they would me, the one cashier yelled that I should go the back of the line again as they are to busy to help with parcels. I am dissapointed and appalled by their behavior and in PEP in general. Furthermore, going back today fetching the parcel again, the lady got my parcel, put it on the counter and told me to wait so that she can help the customers behind me. I was furious! This is not acceptable!!
