Nando's Peri-peri

It was roughly around 4.15 time on Sunday 3 December 2021.We were driving home and stopped by to have some chicken. Our order was an appetizer, one peri chicken sandwich with side , two orders of chicken legs with sides and one order of double chicken legs with side. it was our first visit at the particular location though we do order through skip the dishes . We were served he food and my kid, wife and myself were not much happy with the chicken served and found the chicken to be bit chewy. and told my wife that i should have had asked them to cook it well done. We all ate the sides and had some part of chicken and left it unfinished but had one full leg leftover and decided to take it home so grabbed a box from counter and packed the chicken. When i started to eat the chicken at home i realized that the chicken is raw and bloody in thigh. I did take some pictures and put it back in the box and saved in the freezer. next day i had uneasy stomach and felt as if i had mild food poisoning. By next day my stomach was much better and called the restaurant little after 12 noon where a staff member picked up the phone and i requested him that i wish to talk to the manager and on asking as in what regard i explained the reason. I told him that i m saving the chicken in the freezer and can bring it in the store and show to your manager if required. he took my number and assured that the manager is busy and i will be called later when the manager would get some time. Since then i have not received any call. I normally travel for work and do not have much time to follow up. After not hearing from Restaurant manager i did write an email to Nandos Canada after 10 days and received a quick response that I will be contacted but no one has contacted me as yet. I am attaching some pictures of raw chicken and have it still saved in the freezer and am willing to bring it back to restaurant management if they wish to see it. Very poor experience with food and their follow up.
