Bad attitude and service

First visit - charged me for 5 burgers not 4. Error fixed. Second visit - The onion rings were not in the bag. I called and the person offered free waffle which we did not take up - but appreciated the gesture. Monday we ordered and went to collect - only 2 of the 4 burgers were done - was told I never ordered 4.. no apology no nothing - the person assisting had no customer care at all.
