Poor customer service

Poor service, placed an online order on Thursday for Monday. Order accepted payment processed. They call me on Monday day of delivery 1 hour before to advise they don’t have stock! Left me with 2 options either I pay more and have the items substituted or I take whatever they feel like giving me! Not what I ordered and paid for! Or I cancel the order 1 hour before delivery! They had 4 days to notify me they can’t fulfil my order. Really ****ed off with this service! Woolworths retail park easy rand useless!!!!
