Poor service from MC donalds

Came to the MC donalds Bellville branch drive thru at 19:45 and was told by the lady who assisted that we couldn't order what we wanted on the menu only a Grand chicken,cajun chicken or MC feast because they were closing at 20:00.After I questioned the lady she then said okay there is a big Mac and they can make it,then I came to the window where I collected my food and asked the guy again what time do they close and he first said 20:00 then when I told him that MC Donald's in Parow closes at 21:00 he then changed his story and said they close at 21:00.The staff are turning customers away and it is unacceptable.Poor poor service from MC donalds
