Capitec does not want to release my Money but I sent the affidavit via email. It almost a year now

I'm an Uber Driver and one of the clients Transferred money in my account and Capitec froze my money up until today but Other banks released my money because I explained and sent affidavit. But with capitec I haven't received my R900. I can see it on my balance but can't withdraw it yet I sent the affidavit explaining.
