Pathetic company, pathetic service

Last week Sunday, I went to the builders warehouse in centurion with my wife to buy 2 fire & earth wall paper. I got the wall paper i want, and then I went back home and app**** it on the wall. The wall paper was nice, however is needed extra 2 rolls of the wall paper, so returned to the centurion builders warehouse to buy them. Upon my return, the same type wallpaper I need to complete my job at home was out of stock. I then asked the staff to please search for me the availability of the wall paper at their other builders warehouse stores, and I was told that they cannot be able to search the barcode of the wallpaper I had already bought, as it does not exist. I gave them the slip on the wallpaper I already bought with barcode, and also the barcode on the same wallpaper I already bought and they still tell me that, the barcode does not exit. I then went to the woodlands builders warehous with the same documentation and I was told the same thing that, it does not exit. I went to the sunninghill branch, and I got the same story. Now I am sitting with a half done wallpapered room that I cannot finish, and I will have to unstrip it nad loose all the money I spent buying this wallpape
