BUSINESS OPPORTUNITY NOT HONOURED

I was retrenched and like a lot of others could not find employment . My wife and I decided we should try our hand at our own business. I searched the internet and stumbled on this opportunity offered by Biofuels SA. We were very hopeful and decided to do our research and found that this was something we could do. I completed the application forms and sent them in together with R10000.00. This deposit was made on 26 May 2017. I received a call to attend a workshop/meeting to give us a view of what we will be doing and show us the factory. This was in July 2017 and we were reminded to pay the difference of R15000.00 by 31 July 2017. I have since then not received an email or call as to what we need to do or when the project will start. I have requested an refund from them via email , I have made numerous calls by they all get ignored. These people are *******.
