Woolworths extra delivery charge for nothing

I ordered an item from Woolworths and paid extra for early delivery. The item was delivered 4-5 days after the suggested early delivery date. I sent an email to customer care and they rep**** with an apology. There was no response to my extra payment. Although the amount was not absorbent, the principal behind the error would be to reimburse me. If I enter a store and am short of one rand and apologies will the item be given to me? How many other customer are being ******, this seems like a plan to get more money out of customers.
