I bought a bed on a Sunday and I was told delivery is 2-5 working days from the website . They came back to me saying they can only deliver on the 10th of December, this is false advertising as the latest delivery date should be Friday the 6th of December I’m requesting a refund if they cannot deliver by Friday or an option for me to collect myself , they told me refunds would take 7-14 working days and I need the bed by Friday
