no range and discontinued

some time ago I purchased two carpets 2 x 3 metres same colour for a spare room it didn't finish the job and I needed another two so I kept going back to game and was told that they come in lots and don't know what they get - I asked the manager if he would give me a discount and he said they only discount on discontinued ranges - I found out today these carpets are discontinued and have been for two years now I am stuck as I cant get the carpets to finish the room ! So I have to try and match it up but if they stock was discontinued it should have been marked down I have been backwards and forwards to watercrest store for weeks now hoping they were going to get stock
