Rotten Tomato

I buy from mcdonalds EVERYSINGLE weekend probably twice and i spend over R300 each time i have ALL the slips to prove it and i ALWAYS get horrible results...cold chips,wrong order,half drinks etc.I just ordered a sharebox like always and got a rotten piece of tomato on my cajun chicken burger and the wrong nugget sauce.Ive honestly reached my limit.I always have to deal with bad service and "be happy" with what i get...deeply dissapointed.
