Bad customer experience

I order a birthday gift for my partner on Thursday the 27th of July to be delivered today at his workplace. Kept tracking my order and I just kept getting the same results that the order is being processed. I decided to text them on the chat option on their page and was told my order won’t be delivered because it is out of stock. When I order on the app yesterday there was stock! And on the date that they were suppose to deliver they suddenly out of stock! What makes me angry is that no one bothered to notify me about this issue until I reached out to enquiry. This was for someone’s birthday and I kept the person at work for over and hour from their knock off time telling them to please wait for that delivery. They offered me chocolate and roses to compensate me like really will that start the day over again and will my receiver get his present on his birthday?? I asked for a refund and I’m being told it will be done in 1 to 3 business days! So what should I do in the meantime as I need to get a gift somewhere else? This is nonsense! Clearly this company can’t work with people
