Cash withdrawal

I have a problem every time I try to make a cash withdrawal on the tills of shoprite. It's always same excuses 'I do not have enough cash' try another till. Capital sends me messages on how to save bank costs, which is good and one of their recommendations is to make use of till withdrawal but unfortunately they don't know the inconvenient we experience. The bad service we get from shoprite, I'm only complaining to capitec because I bank with them. Please capitec you might want to re-look the deal you have with shoprite
