Rudeness and rotten box of pies

Today I went to Superspar @Mdantsane North and bought a box of Pies (Mama's Pies brand). When I arrived at home to prepare for my kids ,the box of 6 were all rotten. I drove back to return them and was given a worse rooten box. I asked for the manager and he came , he didnt even look my way or greet, he spoke with the cashier and walked away. I stood there like an idiot waiting for an apology at least for the fuel i had wasted and the risk i Almost put my kids through.
