Hi, not sure if anyone can help but I'll give this a go. I recently placed an order with a company for 2 lots of 500 items. They sent me 2 x 50 and when I queried it, and asked where the other 8 packs of 50 were they basically blamed the IT staff. They offered me a refund, or to send the rest of the items, but claim that all I paid for were 2 x 50 not 2 x 500 so I would have to send more money. The tax invoice clearly states that I ordered and paid for 2 lots of 500 items not 50. Under Australian Consumer Law, can I get them to send the rest of the order? Cheers.
