Order cancellation

On the 9th of June I purchased an electric heater and a 500ml bottle of honey. On the 11th,I received the bottle of honey and called the courier to find out about the heater. They said the honey was delivered from Makro and the heater will be delivered by the supplier which I was not aware of. On the 18th I called Marko on the 18th to find out about when will my heater be delivered. They said they will find out from the supplier ,the next thing I reive an email from Marko saying that they have cancelled my order due to the supplier not having the stock. Makro didn't communicate this with me prior to the cancellation.
