Dont adhered to agreed rule regarding refunds

this group of people recruit citizens to join the group with a payment of R800 and become a owner of a social housing scheme. They also indicate on their application form that if you are not pleased you can cancel your membership and get refunded. It's been nearly 6 months that I asking for my money back from them. They direct me from Mr Andre Jooste to Farell Tempers to Mandy the PA of the president of WHF then again to Andrew Jooste who direct me to Albert Brown but they can not come so far to refund me. They all together collected more than 25 million Rand so far.
