Food Contaminated

Good Day, i am very dissatisfied with MacDonald this time, i love MacDonald, i am a faithful customer for years, i even have a App that i frequently use, but today just now i ordered two meals, first the Oder took so long to get to me MacDonald Kollonade even called me to confirm my delivery address which i was surprised as the previous time the delivery lady just came without phone in, after waiting a long period which i understood, i received my meals and i paid cash, now for my other surprise i got this black horrible thing inside my fries, looks like its over fried chip and that just made me to lose my appetite, i m so angry and i really want to expose these in the social network, its highly unacceptable for me cause its not the first time this happens to me, i even took a picture as proof to show to the head office customer service. i am so ANGRY and DISAPPOINTED,, I EVEN Lost appetite.....i am taking this matter further!!!!!!
