Capitec Bank Forensics department

So on Sunday, the 14th of March, an unknown sender had send a sum of money into my bank, I didn't even notice the notification until like 16 minutes later, to which I panicked when I noticed an Sms 16 minutes later after the money was sent into my bank account. So I logged into my Capitec banking App and transferred the money to a trustworthy friend to keep for safety reasons, as I did not know the sender and was concerned as to how they go hold of my bank account number. I waited for the original sender to contact me and ask for me to rectify the mistake, send back the money to the account I received it from. Please take note that I don't even know the senders account details, the bank notification Sms just displayed the senders Reference. I didn't receive any call on Sunday afternoon nor night. On Monday morning when I woke up, I had decided to contact Capitec bank and let them know about this incident, to which I was given a reference number from the call center to take with to the nearest Capitec bank branch. My Account was immediately blocked. My app was disabled and inactive. I can't login. I can't withdraw money. I can't make any transactions. My friend's Capitec bank account is also freezed and so is my friend's Capitec banking App. We both went to the nearest branch to resolve this matter and try and contact the original sender to transfer the money back into his/her account. We were asked to go and do affidavits, ID copies and all the other required formalities. Our documents were sent to the Capitec bank Forensics department. On Tuesday morning, I received a call from the Captain of the Saps in Kempton Park, and he explained what had happened, that a case of ***** was laid against my Capitec Bank account. The Captain suggested that I meet with the original sender at the Capitec Bank Branch at Festival Mall, Kempton Park. I met with the captain and the original sender. We submitted all our documents and the Captain allowed the original sender to write an affidavit stating that he is dropping the charges against me and all other involved. The documents were submitted to forensics department, in the Capitec Bank Branch at Festival Mall, Kempton Park. The Consultant at Festival Mall, assured us that our accounts will be unblocked in a maximum time of 3 hours... That did not happen, until this day, Thursday, the 18th of March 2021, our accounts are still blocked. The sender's money is untouched. Why doesn't Capitec bank transfer the money back into the original sender's account and unblock our accounts? We need the accounts as they are the primary accounts for both my friend and I. We won't be able to pay bills and survive.
