Rotten chicken at Nandos

So disappointed at Nandos Savoy. On Friday my partner and sister went for dinner, we all had quarter chicken's. We could taste that it was a bit off but we kept quiet because it was edible and I am so tired of complaining, the last time we had to complain, there was a fly in my partner's burger. I took so long to complain because I was sick and didn't have the energy, we all had runny tummies since Friday till yesternight. We buy at Nandos because we chasing quality but ay, I give up, seems the competitors are winning.
