Ridiculous delivery time frame!

I bought a queen size bed online expecting it to be delivered within 14 days. Only to be told that The bed is out of stock and will be delivered in 5-6 weeks. I cannot be sleeping on the floor for more than 5 weeks after paying so much money. Please can I have my money back so that I can take it to someone who takes their customers serious. Stop tricking customers into buying goods that you know exactly are out of stock!
