SPAR sold me OFF products with BAD after service!!!!!!!!!!!

I was a customer at SPAR Paddocks Milnerton and bought a chocolate mousse 1L only to realise when I got home and after opening it and eating from it as a pregnant women , realised that it was off. I then decided to take the mouse back to Morning Ford SPAR which is right opposite my house where I was quite abruptly shown away by the store manager Lisa. I could not understand why I could not be helped at a SPAR right by me and told I have to drive all the way back where I came from which would cost me extra petrol to do I might as well have thrown the mouse away. I did not appreciate the service after Spar was in the wrong selling products that are off.
