Bad customer service

I bought a family meal with them and their burgers tasted horrible.It was like they have been in the freezer for a very long time.I complained about it and they offered me another meal to replace that other 1.The guy I spoke to on the phone I think his name is Charity was very sorry and humble.When I went there to collect my compensation order Charity was not available but found some lady who offered to assist a cleaning lady went to the kitchen as thy were expecting me.She came back told me thy r busy with the order.I could hear from the background a lady named Thuli I think Maponya branch complaining.when i collected the order she was busy passing remarks i nearly left tht meal there when thy had to replace coldrink she shouted from the other side and I quote"she wont get any coldrink as the coldrink didn't taste bad like the burgers😏I felt really small and dont think I'll ever go to the maponya Burger King anymore.It was like I was being bul**** for raising my concern
