biltongmakers.com Biltong Buddy

I purchased The Biltong Buddy (2kg) Home Biltong Maker from biltongmakers.com. The unit does not come with a fan (this is not obvious in the description) and neither is it fly proof. My biltong ended up mouldy and maggot infested within three days. I asked for a refund and received this:

"Again – no refund, the Biltong Buddy is perfect for making good biltong and …. It was you who chose a model without a fan and use the suggestions given to prevent flies.. Please, no further discussions."
