Deceased's account still not closed

Good day, I have a complaint regarding the closure of my deceased Mothers' account. My Mother passed away in November 2021 & to date the funds from the funeral benefit that she and my Father qualified for (due to them having a joint account) has still not been made available to him. My Father is retired & had to pay for her entire funeral without the financial assistance from ABSA which was due to him. In September 2022 their broker provided the instruction to ABSA for the closure of her account, in order for the funds to be transferred to my Fathers' account & to date this has not been finalized. We're not receiving feedback or a concrete reason from ABSA as to the reason behind the delay and to date the service deliver has been nothing but **********. This matter has been escalated on a number of occasions, yet no further response was received. I await your feedback & further steps that would be taken in order to have this resolved ASAP, please. Thank you.
