Account frozen

Hi, I have a problem with my Capitec account which was paused for investigation. Capitec has never tried to contact me or advise me on what needs to be done. I have gone back and forth trying to contact them and have also been to the branch and only then I was advised on what I need to do. I have submitted the relevant documents but still no proper feedback on the way forward. It's been over a month now. I have funds in my account and have no access to my money because they keep saying they are busy with investigations. How long are these investigations supposed to take? I need someone to assist me ASAP
