My account is unfairly blocked by capitec

Unfairly treatment disloyal to me. Capitec freeze my account claim that there is R250 that come to my account on the 16th of March 2023. They freeze my account on the 21st of March 2023. They say that I must do affidavit and copy of ID and bring it to the capitec branch yesterday 28th March 2023 I received my UIF money as the account is closed. When today 29th March 2023 I go there to ask about the account they said my account is total closed will never be open ever again.what I don't understand is why my account is able to receive money if it blocked and never ever work

Another thing why others with same exactly incident as mine they open their account. Capitec is taking sides here and why they did not block the account was sending me the money they say it ***** . Why they are not at least take this R250 money I'm no happy about that decision of close my account please do review this decision
