Hi, I purchased a bed, paid in full, and had to wait 10 weeks for it to be made. On the delivery of the bed, it was not the correct one. I called up and they said that the salesperson (who was the manager) entered the wrong code into the computer and that we now need to pay another $500 to get the correct bed. Do I have to suck this up and pay under Australian Consumer Law? They gave us a price for the bed we wanted and we agreed to it and paid it, now they want more.
