He also selling solar franchise , Retrosol/ sky bridge

Beware!!! You going to loose your deposit!!! Be careful doing business with Retrosol/Sky Bridge/ James McCallum. He advertises a Solar Franchise, which I think is a legit company, where you can pay a "refundable deposit" of R6500. I paid the R6500 deposit, but under certain circumstances can't attend the training. I even gave him a candidate(friend of mine) who paid his R6500 deposit and is going to attend the training( giving him business) I told him I can't attend and want a refund of my deposit. He blocked me on whatsapp and on his emails, I sms'd him and told him I'm going to social media with this!!

I got hold of him using a landline, he told me he's not going to refund me, I must read the fine print on the invoice... It's true, the fine print says he dont have to refund me. Its my fault not reading the fine print, I trusted him, but why after paying deposit the fine print appears on the invoice and not on the franchise documents he first sent me?? I don't know if I must attend day 1 to be refunded?? I don't mind if he subtract admin/service fee, which is fair!! But taking the whole R6500 for doing nothing?? Taking my hard earned money(savings) doing nothing?? Do you think its fair?? What will you do?? He is bragging over the phone he is a millionaire?? But can't give me something back??
