Pie city cashier selling me a pie with no chicken inside when I try to call they drop my calls

I am very disappointed with pie city Ekhaya shopping center Langaville. I normally go there and get myself a pie since i love it. Today when going to work i pass by as usual to get my favorite chicken and mayo and a cold drink. When i arrive at work just after one bite on my pie i just realize that the pie has no chicken inside,its just folded😣. Luckily I didnt throw away the recipe. When i check the recipe it is written that i bought a steak and kidney pie but i asked the cashier for a chicken mayo. I went to search for their numbers on the net and when I call trying to complain about my purchase they drop my calls. Im so disappointed and it is so unfair
