Capitec Investigation

I woke up yesterday trying to transact on my capitec account. I logged in the app only to find out that i can't find my savings account. I thought maybe it was because of a bad network. I retried several times until i visited my nearest branch. When i got to the branch the consultant told me that my account is on hold as they are investigating me. When i tried to ask they told me about refunds from sars which are a large amount. Its true i received cash from our organization treasurer which were funds from sars refunds for our NPO. Now they put my account and also the treasurer account on hold for investigation. My problem is that nobody bothered to notify me about the incident,also sars are not aware of the issue as they audited everything in their possession. Is it a problem to transfer some couple of thousands in the account. I am really disappointed in the manner capitec held the matter. I also told them i have proof for all this from sars but they don't want to hear anything from me. I must wait for their investigation to be concluded though they haven't advised on how long will it take. Am leaving this bank believe me. Am so disappointed
