Poor customer service

I bought a bed from Lewis in Khayelitsha on the 25th of April 2018 and I have been calling and calling with promises that it will be delivered and I even went into the store and the other lady told me they were going to give me Medi-spine as they had no stock of the Edblo bed I bought. I want what I paid for delivered, I have been patient long enough. This is poor customer service. When I bought the bed there was stock available in store but after they were not delivering the bed I went into the store and they told me they had no stock and that means they gave the bed to someone who came after me. Can you please sort this out or give me back my money so I can go and buy somewhere else.
