Nothing accomplished between bank and government systems.

Good day, I urgently require assistance as my patience is running up with bank and government systems. I need to access my daughter's bank account as maintenance funds have been paid into this acc and the card has expired. My daughter is under age and my ex boyfriend opened this account for her as I did not have a Capitec acc at that stage. 4 years ago my ex boyfriend went abroad and we have had no contact and is unreachable. I have make a Affidavit stating I am the biological mother and the ex boyfriend is unreachable I need to access this account. I also have the expired card, my daughter's birth certificate and app**** for an unabridged certificate which will take estimated 6-8 weeks as an abridged certificate is not accessible to me as Home affairs advised the system was not in place the time my daughter was born. So now Capitec still refuses to assist!!!! I am in between the bank and government systems who are blocking me to access my daughter's maintenance money. Where do I go for assistance and how will I have access to this money? Please advise?
