For how long can one run after the national deceased estate department??

For over a year now absa still fails to do right by their customers who have been loyal to their company my late mother has been banking with absa for over 10 years when she paased on we opened an estate late account and submitted all other documents needed from wonderpark branch to the national deceased estate department for the transferring of funds we've called numerous of times asking for progress in regards to transferring of the money the only responses we get is we are still waiting for the master to confirm til today as I state again I'm very dissaponited with the service I'm appauled at how absa treats clients who trusted them with their accounts now that they are deceased they no longer interested in releasing their funds

Absa a resolution is needed asap ***
