The inconsistencies of processes and procedures of Capitec Bank.

I really fail to understand the systems,principles and processes of Capitec Bank especially it being a well established, growing bank. Iv been using Capitec as my business account as I have an events company . In 2015 a close family member asked me for my account number as he was awaiting a payment and asked if he could use my account , I gave him my account and unfortunately R20k of *****ulent funds was deposited . He used R19k and said the R1k he has left are for bank chargers as it was a withdrawal of funds and later my clients deposited money into my account as well as a friend who lives overseas . When I tried using my account I was told that it was under-investigation. Till this day. What upsets me is that money can come into the account as my old clients had this account saved as a beneficiary. I went to the branch multiple times trying to retrieve my funds with no luck. A client of mine deposited another R800 in 2016 and those funds needed to be used urgently. I went to the Capitec Maponya branch with her and the consultant who assisted me was able to take the funds out for me.What I’m failing to understand is why certain processes could be done for me to retrieve the R800 but can not be done for the balance in my account .Again on the 5th of April another R500 was deposited by my son in law for his daughters transport money as he also had this account saved as a beneficiary and I cannot access those funds . It’s been 8 years and this is still under investigation and the account is opened.Why were funds able to come into my account after the incident and a hold not put on the account if I wasn’t supposed to be using the account anymore . Why is it still open with my money in the account . The same process that was used to retrieve the R800 is the same process that needs to be used to take out my R12k+ balance . This is really unacceptable that an entire bank has inconsistencies of processes and procedures that they follow. I need my money that is due to my because I will take this further.
