Nando's chicken marinade have serious side effects

Good day, I've been a big supporter and fan of Nando's for years. I want to bring your attention to your sauce. I love all kinds of hot sauce, from mild to extra hot and especially the taste of the Nando's peri-peri marinade, but there is something seriously "off" with your sauce and this is not related to only one Nando's Franchise. Every time I order the mild peri-peri chicken portion of hot peri-peri marinated chicken I get physically sick afterwards for about 15 hours plus/minus. I thought the issue was with me, but it turned out not to be and I hear of other people with the same complaint. There is a perseverate ingredient or something in your sauce that makes people sick. The pain experienced afterwards from Nando's is quite extreme and I would recommend Nando's to investigate this. Because of this I can not eat Nando's until this has been resolved and I can promise you that this is a general problem and your will or have already started getting complaints from other customers. Hope this feedback can assist you in building a better product. Kind Regards, Pierre
