Wrong item delivered

I have purchased many items from Ted's and amongst those items was a coffee table. Delivery took place on 18/11/2015. Later sometime that week the coffee table box was opened to use however it was completely different. The salesman was contacted and informed of the issue. He had promised to resolve the issue however this has not been done. I had even offered to bring in the coffee table to switch but the salesman insisted that he will sort it out. I have tried contacting the manager today as I am tired of contacting the salesman. Manager seems to be too busy or out of the store. This is ridiculous and unacceptable. Its Christmas tomorrow and I have a large box in the way that I cannot even use.
