Edgars online order taking more than a month with no feedback from them

I placed an order #*** on the 15 May 2020 and today is the 15 June 2020 and I still have not received my order which is winter clothes for my kids. When I call I get excuses that it will be delivered the following week but I am still waiting and all of a sudden I look online and my order says cancelled. Who cancelled my order and when will somebody be calling me back as promised so many times. Quick to invoice as the amount is already on my statement.They said my order will be expedited but still nothing. The agent now tells me that my order was cancelled as they don't have stock of any of the items 22 items. How can this be and why doesn't anybody inform me and why does it take a month to let me know. This is pathetic
