Incompetency at Information Desk

Made a purchase today at Game Stores (Kenilworth Branch). Before making the purchase, i went to Information to ask if i can make a purchase at the Kenilworth Branch on behalf of someone else who is in Stellenbosch and then that person will collect the item at the Eikestad Mall Branch. The information desk consultant tells me "Yes, you can do that, just go to the cashier and pay for the item and tell her what your request is. Then take a picture of your slip and send it to the person in Stellenbosch as proof that the purchase was made so that they can collect the item at Eikestad Mall Branch" . Did just that, the cashier looks at me all confused and tells me that that request cannot be fulfilled. So i tell her that what the information desk consultant has told me to do. The cashier then calls another staff member who also tells me that this cannot be done. Note, that i am pressed for time as i only have 30 mins lunch time. The new lady then goes over to the information desk and speaks to her, they then call another lady, they confer with each other and then calls another lady to assist. What should have been a 15-20 min outing ended up being 45 mins. Eventually, they all find someone who can help them. She then tells me that my purchase will have to be reversed as they have to check with the branch in Stellenbosch if they have the item in stock then should they have the item in stock, place an order, then pay for it which will take about 15 mins. Am displeased with the incompetence of the information desk consultant, had she told me this from the start - all that followed could have been avoided and i had not returned back to work late. Kenilworth Centre Game Branch will not be seeing me there anytime soon.
