Complain about pick n pay, Kwamnyandu

Yesterday, Wednesday morning I bought 3x1 kg wooden s**** margarine at pick n pay, Kwamnyandu, because I was going to bake at night only to find the the margarine are stale????????????????. It 8pm I have cake orders going the following day. Can you imagine my frustration, I had to call friends and family to see who can borrow me margarine. My aunty in Isipingo had extra I had to drive from uMlazi CC Section to Isipingo to get the margarine and come back to bake. Time and petrol is waisted unnecessary. Today I went to pick n pay to return the margarine, mind you I'm supposed to be working it's Friday I'm busy, again time and petrol is waisted unnecessary. I explained to the manager how I've been inconvenienced I'm asking for a compansation voucher. He said it's not in their company police. I guess it's selling stake margarine that is in their company police????I'm not happy with their service. I'm still requesting a voucher to cover my petrol.
