Disgusted by the chicken

Hi I bought my family a party mix at hungry lion watergate mall in Mitchell's plain and I order half Spicey zamba and half normal but Damn non of that chicken was worth my effort standing in long lines and waiting for more than 20 minutes just for an order and was not advised of the waiting time...then finally you get home wanting to have your supper half of the chicken was very dry and the other half was so oily I could fry more chicken in there..how to you do that too your customers that supports you continuously your food is bad
