Was served rotten chicken

on Saturday the 11/04/15 I ordered a full chicken meal and asked for 1 portion to be the super peri flavour and my meal came to me 1st I initially got a little smell however I ignored it and started eating only to have a couple bites and realised the chicken was totally off I called the manager who took it away and confirmed it was indeed off however I was never aske if I want anything else a few minute later they brought me a meal I paid for it and left the manager never took my numbers or anything to find out if the rotten food made me sick I called customer service twice and I am still waiting for an explanation imagine if it was our kids who ate that what do they know about rotten food BARCELOS YOU HAVE LOSS THE PLOT COMPLETELY NEVER AGAIN WLL I EAT AT YOUR STORE AND I WILL TELL EVRYONE MY EXPERIENCE
