Rotten service from FNB deceased estates

We are winding up a FNB client's deceased estate. On 29 August we advised FNB deceased estates department via email that the client has passed on. We forwarded all the documentation they called for which was telephonically confirmed as having been received. Now exactly 2 months later still nothing has been done to close the accounts of the deceased and transfer the funds to the estate bank account. We phoned the deceased estates department and they said they would forward our case to a team leader for action. If we did not enquire today who knows when FNB would attend to the case. The call agent was very helpful but she is not the elephant in the room -- the back office is utterly useless in my view.
