No Refund for order I never received

Beyond dissapointed with the service (or lack thereof) I received from The Athlete's Foot SA.

Placed and paid for an online order on the 20th of October for an item that was advertised in their email newsletter. Four days later I was sent a very brief email telling me the item was no longer in stock. Disappointing... but ok, whatever.

- Emailed them on the 27th of October asking when I will get a refund... no reply. - Emailed them on the 30th of October asking when I will get a refund... no reply. - Phoned them on the 31st of October to ask when I will get a refund, apparently it was being processed. (Whatever that means). - Phoned them on the 2nd of November and was told owner will eft me immediately. No refund came through. - Emailed them on the 6th... no reply. - Emailed the owner of the store on the 6th (after they refused to give me his contact details and only his email address).... no reply.

It wasn't even a big order. Under R500! It's not even about the money, but how does a business like this take your money for an item they don't have, that you never received and not pay you back? I'm assuming I am never going to get refunded now.

How is this ok?
