Inept Mamohau ta McDonald's Zastron Street, Bloemfontein

I placed an order at McDonald's Zastron Street, Bloemfontein and I was assisted, a lady named Mamohau. I had the decency to show her a WhatsApp message of what I wanted. Instead, she did not give me all that I wanted. Where am I gonna stop to order food again for my kids? Such incompetence is unacceptable!!!!
