You can start by looking at your receipt if Woolworths charged you full price for items on sale. Verify the error by matching the receipt with the posted sale prices to make sure the selling price wasn't omitted.
Ask Woolworths customer care next. Clearly state the circumstances, mentioning the items, the posted sale rates, and the charged amount. If at all possible, send copies of the sale advertisement or any other pertinent material together with a refund request for the price difference or a price change for your next purchase.
When talking about the matter, keep your cool and polite demeanor. Should the problem not be immediately fixed, follow up with customer care or, should needed, escalate the matter.
Should you still be unsatisfied, think about expressing your experience on Xolvie to assist others and maybe inspire Woolworths to act.
