poor service

Good day i went to spar @gauteng jeppe street. I bought a take away ready packaged. i gave it to my child as the child was consuming, i was driving after few minutes the child complained about the stomach ache i checked the package and find out that the food was expired. for health reasons i drove back to johannesburg from pretoria , only to be humilated and disrepected by what so called store manager, blaming me for everything. the only thing they could do was to give me a mere R20.00 as if could drive all the way for that not considering my child that was sick and travel costs. i am so disappointed because even the food was expired written on the product. i had to buy meds and was my ptrol. cell number ********** 108
