I will never go to this Mc Donald ever again

I went there sometimes during the week last week to buy a Grand Spicy chicken burger, but I wasn't happy with bad service I received and mostly the worse burger I never had in my whole life. I had to throw away that meal because I wasn't happy and it was a take away so it was late for me to go back there. I posted the complain on their page on Facebook and they didn't do anything about it instead they deleted that page.
