bad service from ABSA

I administer deceased estates I have several estates where the deceased held bank accounts with ABSA I have forwarded the relevant FICA documents to the national deceased estates department of ABSA for some of the estates it is now going on 6 months and still no response. As much as I understand that they are behind schedule due to the masters office being offline, this kind of waiting period is unacceptable! I have beneficiaries who desperately need money and we can not finalize any of our estates as we have no information to go on. I need someone at ABSA to help me resolve all of my cases and not just keep me in the queuing system as this is clearly not working out!
