Online orders

Ordered laptops online as the site stated "Online only" once ordered and paid, i received an email they don't have the laptops in stock, this was on 6 May 2020, i needed the laptops urgently for business use during these troublesome times, after phone calls and no confirmation on when i will get my order, i decided to cancel. This corporate giant have been sitting with my money since 6 May, they do not respond when i send emails requesting my money back, this is what these corporate giants to do the consumer during these troublesome times, they take our money, is selling something that you don't have not against the law unless you stated you don't have it, i paid them with my money not someone else's money.
