Poor customer service and lack of stock

I ordered some items at the store but was told that the dining room chairs I wanted weren't in stock. So I ask, why have them on display. So a couple of days later I check for different chairs on the website and call the store to ask them to add it to my delivery. Never heard back after they sent they would add it. So I ordered it online only to be sent an email saying that chair is also not in stock to which I reply asking what is in stock so I know what I can order. No response. I send another email the next day asking for feedback as I have already paid for the chairs. Again no response. Days later I'm now at a point where I don't know if they have any chairs at all or just displaying items for the sake of it.
