Tasteless nandos

I have eaten in Westwood Pavillion gateway ,and the one at St John's Ave,all was on point with freshness and taste ,however I bought Nando's from Pinecrest mall on Saturday,I was just a boiled chicken that was white in colour ,no flavour ,it was actually very gross ,I had to through it in the bin .very disappointed.im actually put off from eating Nando's now
