Robotics or Cyber ****

This company sells Robotics Kits with training for children. One of their sales hooks is a 30 day money back guarantee. I unfortunately bought one of their products. I was unhappy with the product and more specifically the low quality of the training. I reported it within a week of receipt and they collected it. It is almost two months and I have still not received my refund. Wiets Burger from the company used to reply to communication but now my calls are no longer answered and my emails remain unanswered. I am left to believe this is a ****.
