I want my money!

So I used to have a capitec account which was my own personal account in 2022 a few family members and some friends decided to start a stokvel where people would gain interest so it became a money lending business . I was chosen to be the treasurer, so there was a main account and other two accounts of which one was the stokvel account. Whenever money came in and I informed them then a member would request funds so it used to be paid to the given bank account everytime. My account was blocked without any given explanation. A member paid money into the account mistakenly of which I had to replace om from my own pocket. I've called capitec since and no answer was given. Earlier this month I thought I'd check to see if the account is still active and to my surprise it was. I went to the branch and they told me that there's no note or reason for the hold on my account since 2022.. I did follow ups and got a response via WhatsApp that there was "mule activity" on my account. I advised the consultant that it was a stokvel so there was absolutely no mule activity but people who was willing a part of the group. I provided proof of the WhatsApp group chats and requests made by members back then and responded via email to the ***** department. I was told Tat is 3-5 business days it's been 8 business days now and still no feedback and my account is still frozen. The money that was paid into it is also gone with no explanation. I want answers and I want my money that's left in the account as it belongs to me. They can close the account for all I care because what "investigation" on an account lasts so long?? Plus no contact from the bank with a proper reason even though proof was provided that it's not "mule activity" this is pure daylight *******!
