Blocked account

In March 2023, the father of my kids deposited an amount of R30 000 into my bank account for my children as he has not been sending me money to assist with the kids for a few months, my account was blocked by capitec after that transaction and when I went to the branch to enquire was asked to write and affidavit to acknowledge the receipt of those funds, I did that and submitted every thing I was asked to by capitec, weeks later I tried to follow up on the matter when I got to the branch was told I must submit another set of affidavits from me and the sender this time the documents must mention that I didn't know the funds were *****ulently obtained, again I did that submitted the documents, again after a few weeks of no feedback from capitec Bank, I went again to the branch to follow up, guess what, was asked again for an affidavit from myself that states why the funds we deposited into my account which again I did and this time I attached and emailed to *** and the response was an automated email, ok . I made a call to the help desk again to do a follow up, guess what, the lady on the other side of the line tells me again, to go look for the father of my kids and ask him for an affidavit and a copy of his certified ID which I already submitted, I want to know, how many times must I obtain affidavits and ID copies?? Everytime I try to do a follow up in dictated by capitec to bring yet another affidavit. How many affidavits does capitec need from me for them to assist me as their client?? Are these documents even used by cqpitec to investigate or they just enjoy dictating to Mr and tell me to bring a different affidavit everytime I make a follow up since they won't even come back to me with the outcome of their investigation?? I don't feel assisted by capitec at all. At the end of the day, the money that was deposited into my account was owed by the person to my kids, but where he got it, it's got nothing to do with me, and I can't monitor a grown man and ask him whenever he sends me money to feed my kids, where he got the money,

Can someone assist me with this because I need this account to be unblocked because also I get paid my salary into this same account My life is stuck at this point. Please assist I'm not satisfied with the service at all.
