ARE EGG SHELLS PART OF MADEIRA INGREDIENTS???

Im very disappointed with the quality of food I got from Spar Groblersdal Mall, this is directed the the confectionery, On Friday 6 August 2021, I purchased a Madeira loaf , only started digging into it the next day, and as I was chewing I could feel what seemed like pieces of egg shell in the cake, ag ignored and told myself that ag maybe its nothing serious. Its Monday and I decided to have another piece from the Madeira Loaf for breakfast and I came across a another bigger piece of egg shell, this just goes to show the lack of hygiene and competence from the Confectionery staff, I must say I am very disappointed in the level of quality received from Spar, I dont know Spar to be this reckless....
