Unkept promise

I bought groceries at Checkers Norkem Park. The next day when I was preparing breakfast for my family the brown bread out of the two loaves had green and white mould. I took pictures and sent them to their customer service and Sixty60 emails on the 28th of May. A few days later I received a call from a lady who promised to refund me with a voucher of R30 after the matter was referred to her by a nice gentleman called Romano, and I’ve never received it. They shouldn’t have bothered to call and make empty promises. I support their business on a weekly/monthly basis but I have not gotten a resolution for such a small issue. Businesses need to take consumers seriously and sell us fresh produce and products, especially because we pay for this service and it can affect our health, especially small kids preparing food for themselves without supervision of adults.
