Placed order online stock showing. 3 days later receive email main item cancelled no stock? I sent email stating cancel whole order as not satisfactory. 2 days later receive email stating another item cancelled, I tried to ring 1300 30 mins no answer. Sent email stating cancel order as a third of items cancelled not satisfactory, items go together. 2 days later receive email item to arrive via post? I dont want the ONE item why would I pay $12.00 delivery for item I no longer require when the others that go with it; are out of stock!! Get organised Spotlight...IDIOTS
