McDonald's complaint phone?

Let me tell you, when I complained to the McDonald's store manager, he said no way. So I had a hard time finding the complaint number and getting through. The customer service staff has a good service attitude and said to give me a reply within 3 working days. As a result, half a month passed and there was no response! Only then did I know that McDonald's didn't care about you at all! Do you want to eat or not? Can't complain. Are you biting me? From then on I decided not to eat McDonald's! When I walked into the KFC restaurant, the big sign read impressively: "If you have any suggestions or comments on our service, please call us. . . Also welcome to visit our website to make complaints and suggestions! " In any case, this is a responsible enterprise. I'm not competing with my peers to crack down on McDonald's, but their staff have a poor attitude. Thanks for eating so many times, I finally bought a chicken box and asked for a packet of sweet noodle sauce. The orderer also asked me to ask the manager for it. I bought a watch last year! ! !
