Do not order from Game online - rather go to the shop

Order Delayed #*** - Game online and next day delivery is a ****. They sell items online, show as if they in stock, they take payment, and two hours later they send you an email about a "so sorry, delayed consignment, we will advise you when the order is read"'. Why did they accept payment if there is no stock? The cellphone I ordered and paid for today is a birthday present that I need to hand over to the child on their birthday which is on Monday. I could have gone physicallly to the shop if I was advised before paying that there are issues. I dont have any more money to buy the gift for Monday.
