I just want my money back

I placed an order online @ Karibaa the 27th of May 2022. Afterwards they send me an email saying it takes 10-30 business days, on the 2nd of June i got an email saying that there are no stock! And they would refund me it will take up to 14 days i must send my banking details. So i emailed them asking when can i revieve my refund and they keep on sending me an email saying that a support rep will be in contact with me within 48 hours its been 3days still NOTHING. Now when i try to email them my email comes back saying the email address is an error. PLEASE PLEASE HELP. This order was a birthday gift for my mother and i paid R848. And the bad thing about is that iam not working so this was my LONG TIME saving money and now its LOST 😔
