Untruthful company

The owner of this company is ****ming people, I purchased his robot last month June even today I haven't received anything but my money is gone, I called him last night to find out when is he going to deliver or refund my money, he insulted me and threatened. Kindly assist with this company because he's still advising more business but what he do is *****ing from poor south African. His email address malopekatlegojoseph@gmail.com. His name is Katlego Joseph Malope
