Rudeness at Spar Universitas Bloemfontein

Yesterday we bought Spar freshline Roosterkoeks from Spar in Universitas Bloemfontein. The expiry date was showing the following day however they had mold. We took them back to the store and we were concerned that a pregnant person had already consumed 2 when we picked the mold up. A manager at the store could not even come out to explain or attend to our complaint, he said the mold will not do anything to the pregnant lady, we must google it. I have never experienced that level of unprofessionalism, rudeness and inconsideration. I am appalled to say the least.
