Pep service

I went to Pep to send something via Pep paxi something was purchased and the smallest bag was paid for by the buyer when i get there the store in Westwood mall the staff behave as if they are forced to work there ,Firstly the attitude and secondly they are plain rude I ask the lady for the bag and the response I received was oh no small bag I said i need the small bag as I am being paid to send that she was so rude and acted as if she couldnt hear me busy with something more interesting no courtesy of telling me when they will get these if a store is out of stock of a service like Paxi ,Paxi needs no to inconvience the client and give them the next item in terms of the bag and that price ,you advertise a service and then rip people off with the excuse of no bags costing them almost double in a time like this is not fair,actually its sad she with her attitude did nothing took the bag and just put it aside i had to even ask her if she was done i mean really why ? Pep needs to refund me the R40.00 as the lack of bags has nothing to do with me and I was not even advised when they will receive them so every person will be charged a higher amount because it poorly run service the staff really need to buck up there as this is not the first time i noticed attitude in that store
