Karibaa always out of stock

It seems everyone buying from Karibaa are experiencing the exact problem. You order and then get a message that the product is out of stock!! How can a portal like Fastpay allow a company like this? I had to give my banking details for a refund, but up to now has not received anything. They do not answer their phone, it goes onto a voice message. Bad bad bad. Something has to be done against them and force them to remove their online sales.
