Disgusting customer service(disappointed)

Nando's cresta is now gone to the dogs,manager named sipho does not give 2 hoots about his customers so I wonder how he even has a post,I eat at nandos cresta at least twice a week spending a minimum of R400 at a time,for the last 2 weeks every order I made was a mess and when I ask for it to be rectified I must get into an argument,I guess it's the last time nandos cresta will see me,absolute disgrace to the brand you represent.
