makro wonderboom

I have a gift card from Makro. We tried to pay at till 4. The lady at the till said the gift cards is off line she will call the supervisor. He came with a ****ty attitude. Not even greeting us and said there is nothing he can do turned around and walk away. We were so humiliated! He did not even try to help us with their product! We left the store empty handed red in the face. If i knew this i would have asj for a gift card at another store!
