Better late than never resolution of Woolies Food pricing discrepancy

Went to Woolworths Food Mall@Reds on 5th March and fell foul of the shelf vs scanned price discrepancy problem. My understanding, and experience at other Woolies Foods, in such cases is that the said item is free and any additional same product price difference refunded. Supervisor however had other ideas and just refunded difference; saying that was the policy. I subsequently e-mailed customer service about the issue and over 2 weeks later...yes 2 weeks...was told to contact store manager Rhoda Chetty who in turn provided a voucher to the full value of the items bought. A satisfactory end to an otherwise unduly long resolution process.
