False Speedy Delivery Promises

I keep getting emails from Decofurn to take up special offers and one of the catch phrases is "Super speedy delivery".

Based on this I placed and paid for an online order. Only after your order do they state that delivery is between 5-7 working days!! Nothing speedy about that especially as I will be leaving for overseas before that time is up. Seriously false advertising and now I'm stuck with a paid order which I won't be able to take delivery of. Their call centre agent dismissed me in a do not care attitude and said it is what it is....shocking!
