My money is not accessible

A friend requested to transfer money into my account and now I cannot get access to my own funds ,they claim that there were ********** transactions in the account made which from my knowledge the were none ,there is not even a case number I have been stuck in the Eastern Cape and kids cannot go to school because of this so called investigation. The investigation takes 14days I just want to know from Capitec where are we to sleep with the kids and should the kids not find a school will they be come accountable. And based on what grounds is my money withheld
