Honey Farms CC do not deliver

In December I contacted Emile van der Linde of Honey Farms CC to come and remove Wasps at my house. Emile immediately responded with an invoice for the cost of the removal and added that if I pay now, they will be on site the very next day. Paid him on 29 December 2015 and since then he has not been on site nor repaid my money. After numerous contact sessions, he promised he will pay back the money and today I have not received a cent. I would just like to avoid other people falling for the same trick as this is not fair to any one.
