Want my money back.

Good day, my issue is with a company called Sekelanathi networks. I was introduced to it by a friend, she told me about an investment opportunity they had and I decided to invest R10 000 with them, I was sent a contract from them and they promised that whatever may happen in the investment they promise I will receive my initial invest always, suddenly they stopped responding, their phones ring unanswered, they don't respond to emails and messages, last week they sent email's saying they can't suddenly promise initial investments like they promised in writing prior to that and the rest of the company has distanced itself from their shareholders and I don't know what to do anymore. The name's of their directors are Tumisang Baloyi ********** 510082 and Anathi Tahobonga ********** 082085. The company registration number is ***.57 and the company contact details are ********** 951 and ********** 367. Please help, I am desperate
