Xmas order promised but not received

Placed an order on 14th Dec as their site falsely advertised that 'all items ordered before 19th December are due to leave in time for Christmas', I messaged the company 3 days before Xmas as I was concerned I hadn't received the items or a dispatch email and one of the items still read 'in production' on their site. I received a reply saying 'expect delivery by Friday/Saturday' - it didn't arrive.
Thoroughly disappointed that this company did not honour their message or their advertisement on their site. Had they have been realistic about delivery dates over Xmas for their customers then I would not have ordered from them in first place. Not good customer service at all. Not even an email to apologise the order wouldn't be dispatched in time so that I could have bought other Xmas presents instead.
