Selling something that they do not have

This company sold me a \Las Vegas"wall unit. The deal was done and the deposit was already paid. The consultend informed me that she has made an inquiry and has found a new wall unit at a Capetown branch and delivery could be from 3 to 8 weeks. After 3 weeks I made a enquiry on the 29 August. The sales Rep was not present and I then spoke to the manager. He informed me that the wall unit that they had sold me was discontinued and that there is no new models available. I should settle for a demo model from Bloemfontein or a more expensive model. This company showed no intent of assisting satisfactory and I required a refund and cancelled the deal. I have no trust in this company because they have no idea what is going on within their own company."""
