Woolworths does not honor their deals online

Disgusting service from WOOLWORTHS order the 3 pairs of wedges online on black friday (3 for 2 deal) only to receive 2 pairs of the wedges I have been calling the customer care number to request my 3rd pair as they are out of stock on that pair I ordered. I have been requesting to change that pair for another pair of the same value that where on that deal and customer care are saying this is not possible.

WOOLWORTHS please honor your black Friday special and do not punish your customers for your stock levels
