Unprepared meal

On the 14th of October 2017, my pregnant girlfriend and I visited our favourite restaurant which is Nandos but this time we went to the one at the Phoenix Plaza. Like every other time, we always ordered full meals and always asked for extra basting and for the chicken to be well done. We placed our order, sat down and about 15 minutes later we received our meals. Upon eating my girlfriend who's 7 months pregnant noticed that the chicken was ****** and uncooked. When we called the waitress she took her meal away, with us assuming that she'll bring us a new meal because the chicken was quite raw, however all she did was take the chicken away recook the same one brush it up with sauce and brought it back to us even thou there was evidence of a ****** vein across the fillet of the chicken which was absolutely disgusting. The main reason why we posting this is because when we asked for her to give us a new chicken she said she had to speak to the manager, which she did and then brought back a new chicken more than 30 minutes later. I had to then leave my food and wait for the waitress to bring hers. By the time the food came we had lost our appetite and became very irritated with waiting so long. The very same night my girlfriend was up the entire night vomiting cause she was absolutely put off by what she had seen and the thought of her knowing that she ate parts of the chicken was even more upsetting. We had to take her to the doctor the next day and upon doing so we found out she had food poisoning and she couldn't be treated due to her being pregnant! We are absolutely disappointed with the staff at Nandos Phoenix Plaza. Because we never experienced anything like this before at any other Nandos franchise.
