Foreign/ Suspicious Substance found on food.

<p>I purchased hamburger rolls on Saturday at the Pick n Pay by San Ridge Square , Midrand and to my shock found a strange substance on a few of the hamburger rolls.</p> <p>Seeing such a strange substance on a product I regularly purchase and consume from a place I thought was very reputable was absolutely shocking as I have no idea what the substance could possibly be.</p> <p>I asked the manager to investigate what the substance could be and how it could have ended up on the rolls and to my dissatisfaction was not called back and when I called Pick n Pay I was told it was some substance used in the baking process of making the rolls which I do not believe. </p> <p>As a regular Pick n Pay customer I am really dissapointed with firstly seeing such a strange substance on a consumable good and the level of feedback and response I was suppose to receive. </p> <p> </p> <p>How do I trust purchasing Pick n Pay goods in future?</p> <p> </p> <p>Very dissapointed customer.</p>
