Misleading Customers

The staff at the store sell you furniture they dont have , i bought a bed on Saturday and i clearly stated that i needed the bed delivered on the same-day before i even made the payment, after paying i was then told that they no longer had it and i had to move in to my new apartment , long story short, the bed hasnt been delivered till date and im having to sleep on peoples couches, the staff at the stores just told me they cant do anything
