Never buy from these people

I lay byed a mattress from The Bed Shop Southdale and was told to collect from the warehouse by the owner, his son or the manager. I refused to collect from the warehouse because that's not where I made my purchase. The morning before collecting from the store I sent a picture of my invoice with the description of the mattress asking the manager to confirm that it's at the store so that I can arrange for transport to collect. His response was yes, I can collect from the store. I get to the store to find the wrong mattress. According to the manager the mattress I ordered they didn't have in stock, the factory is closed and there will only be availability in January, after the holidays!!!!! Meaning, in his sick mind I must just accept what's available. I requested for my deposit to be returned and he refused.I was told to take the mattress for now and was promised that the correct mattress will be delivered in January when the factory reopens.That remains to be seen. My worst experience ever doing a large purchase.!!!!
