Item removed from order with no consideration or communication on what would suit me best

Wow I am so disappointed! I ordered shoes for my dads birthday a few days ago and the day before delivery I get an email saying they have been removed from my order because they did not have stock and I will be refunded in about 3-5days! So not only do I not have a present for my dads birthday but I have no money to buy him something else because Superbalist has made a mistake ... This is a joke. I Contacted them to find out if there is maybe something else I could do like a credit on the app so I could get something else and I received a generic reply apologizing for the inconvenience and there’s nothing they can do. This is also not the first time this has happened... a few months ago I ordered a carpet and upon delivery I see the carpet I ordered is not what I received. It was a completely different carpet. So I phoned to return it for the other carpet only to find out they don’t have any more! How can a big company like this have such a careless response to their customers when they are the ones that have made the mistake. I would have totally understood if this was the first time because yes times are tough but it’s not. And no effort was made at all to fix the situation on their side. Very disappointed
