FNB - NO Assistance or communication on frozen account

IN SHORT: My children's youth investments accounts was frozen. I've reported this to FNB early January, advise was that I needed to fica their accounts at the bank. End of January I did go into the branch and FICA both accounts, I truly do believe that the lady who assisted me at the branch did all that was necessary. In the week thereafter the one account was "unfrozen" but the other stays frozen. I reported this numerous times, Compliant case nr ***. On the 16th of February I've reported this on Hello Peter also, but on Hello Peter FNB said they will reply privately.... But privately I received a confirmation of the case number, but NO OTHER RESPONSE and the account is still frozen!!! This have taken so much off my time already...... So disappointed
