Horrible experience

I had an issue today with the customer service received at McDonalds Newtown. I went to the shop to claim my loyalty points to purchase a chicken foldover meal. The app deducted my points and after enquiring and letting the line manager know that the app took my points and I can't claim the meal, her response was that she didn't know what to do. This left me in a predicament because not only didn't I have lunch, but now I have to wait for God knows when for the points to be sent back to me. Such incompetence is so annoying.
