POOR SERVIVE DELIVERY

I cancelled an order on 05/12/2023 after waiting for more than a week for it to be delivered and today I get a response that unfortunately they had to cancel the order due to whatever reason. They knew long before the 5th of December that they do not have stock, why did they not inform me about it? Nowhere is it mentioned that the cancellation never took place when I requested it and now I have to wait another how many days for the refund to be processed for an item that was bought on or around the 27th of November. What is going to happen to the people that did not do their jobs!!! This is totally unacceptable!!!!
