Poor service

We went to McDonald's late at night. We were served buy the most unfriendly person . I wanted to enquire about a promotion they had as I was interested in the toy I wanted. She told me they have no stock of it I prompted her for more info on future stock but with no interest pointed to her manager whom she didn't bother to call till I insisted she call for as I couldn't go behind the counter myself. The person identified as the manger never spoke to me she just spoke to Prudence and carried on experditing orders at the drive through. I then had the floor manager Thuli Marupta who then after I complained about my dissatisfaction tried to do service recovery. After speaking the floor manager I stood waiting for my order and observed Prudence's interactions with other customers and saw that her attitude and body language shows absolute disinterest in her job or the customers she serving. The entire time I was at the counter even after she heard that I was complaining about her she wasn't intrested in coming to apologise or try to explain herself or behaviour. It's a real pity that Prudence is failing her team as their efforts to achieve customer satisfaction are dropped.
