MCCafe deal no longer works

Since I updated, my punch card for the coffee doesnt work. Just went in this morning ready to use my free coffee and it was gone. Didnt argue with the lady its only a dollar after all. But then even after she scanned it a few hours later I checked it again and it didnt register the coffee I just bought. Tried deleting and reinstalling. Same issue. Dont want to put a fuss over a dollar coffee but is inconvenient. Pls fix asap.
