Blocked my account for no reason

Capitec bank just did me the worst thing ever, I'm so stressed and drained... End of July, Capitec bank encountered a technical problem and after that they blocked my account for no valid reason, I went to the branch and they told me to submit an affidavit explaining what happened, since they told me that they blocked the account because of the money I received on the 29th July, I submitted affidavit and my ID, after that they told me that it should be sorted within 14 days, but after that they didn't contact me, I went to the branch again because I had to pay bills and pay for my credit card I have with them, they said I can pay inside the bank, they ended up blocking my account permanently, I don't even know what I should do now, because there was my money in that account but they refused to give me back and besides the money, I use this account for all my businesses because it's was user-friendly, I'm so stressed and hurt by the fact that other people which had the same problem as mine already have access to their accounts but mine is not. How can this be possible? How can they just close my account with the money inside, my money? 😩😩😩
