Burger King Cape Gate ripped me off

I Am livid and furious at Burger King Cape Gate. Shocking service and order totally wrong. I paid just under R60 for a Spicy fierce crispy chicken burger meal and got the small spicy double beef burger. Only noticed this when i got home. Try to phone them but they do not answer their phones. This is shocking, as i get the wrong burger and to top it up it one of those small two bites burgers. This is so wrong. I'm ****** livid and **********. This is what happens when you employ cheap labour with minimum school back ground. Burger King Cape Gate will never see me again and I will go on every platform for people out there to be warned
