Fnb late estate department. No help!

I am executor on my fathers estate and he had an account with Fnb, I went to the branch beginning of March 2024 to transfer funds from his account to a late estate account and I was advised on 7 to 14 working days for the money to be transferred. I called back and emailed for an update on the 25th of March with no response. When I called back in April I was told be call centre agent that it it takes 30 working days for investigations to be done and by that time I had already surpassed that 30 days…I called, emailed the whole of April and May and the agents advise on the same thing that they will escalate the matter to managers and no resolution or response or even feedback, I have to call and wait a long time before i speak to anyone. I emailed ralton which a manager or team leader with no response it is now june…it’s been 4 whole months with this issue, it is extremely frustrating as I cannot fathom or understand what is the hold up because the money isn in the account, the investigations are long done the only thing they have to do is transfer the money to late late estate account, and it’s really sad and frustrating because I mention a thousand times that I have commitments that need money I can’t keep borrowing from people while I have something that belongs to me, I do not know what I have to do at this point I’m beyond frustrated and angry. FNB is terrible at prioritising clients and my dad was a loyal customer for many years. From March to June! Beyond ridiculous! Very frustrated and angry. No help at all
