Online purchase, paid, 5 days after no stock and refund takes 15 days...

Paid 1800 for the shoes. Waited 5 days and no response. Send an e mail to find out what is the status and been told they don’t have stock and therefore a 15 days of refund process starts. It takes the client to follow up on the purchase 5 days after the payment and wait another 15 days for money to be refund. My first time buying new balance product and no more business from me for sure.
