WANT MY MONEY + INTEREST

In 2016 I did an investment with abovementioned company with Franel Oosthuizen and his wife Melenie. I gave them time till now to come back to me but still no response from them. I sent them several mails and whatsupps but still they did not come back to me. I think I gave them enough time now to sort everything out and thats the reason I take further steps as I gave them the first amount of R5000 and then for another person R4000. PLEASE HELP!!
