Capitec closed my bank account

Capitec froze my bank account without a valid reason. I was shocked to find out that my account has been frozen. Capitec told me that my account has been frozen because I am operating a pyramid scheme. I asked them where are these accusations coming from. They told me that people has been depositing money into my account. I told them that the money was deposit by my cousin and my two colleges. They told me to come with proof of deposits. After I had given them proofs they told me that they are investigating the matter they will get back to me after 2 weeks. When 2 weeks had passed on I went back to Capitec to ask for feedback. They told me that my account is permanently closed and they can't discuss the matter with me anymore. I am very disappointed with Capitec service.
