******** with False adverti*****ts

Lewis stores are practically ********, They sold me a bedroom suite that they don't even have and i got to find that out after i had paid R10 000 for it, for two weeks now i'm calling them , sending emails but no one is bothered to deliver what i had bought. they have false adverti*****ts on there catalogs once you have made payment they ask you to choose something else because they dont have what you bought. I want what i payed for
