Stock or no stock please make up your mind

I ordered a bed on Wednesday 31 January 2024. When I contacted them so find out about delivery I was informed it will be 1 or 2 days and the order is ready for delivery. Today when I query delivery I was informed that they dont have stock and need to "upgrade" to another bed. It will take another 3 - 5 days before delivery. Why not inform me that you dont have stock? Why telling me the order is on its way if it is clearly not the case. The 1 or 2 days turns to more than a week now. This is unexpected. Then after 8 to 21 days they will probably have another wolhaar story.
