I am done with Woolworths

Woolworths has continuously failed to prioritize my query. I made a Purchase on the 28th of June and they still haven't resolved my query. Exactly a week ago they promised that they would refund me in the form of a voucher and add R100.00 as compensation. It is 7days later and there is no refund to that effect. Had it been a person from a different Race or Demographic they would have acted swiftly. I am done with Woolworths.
