Disappointed in FNB life cover service, and Unresolved ********** transaction against my dad who is a pensioner

I have had such a bad experience with FNB lately. I took up a fnb life cover a few months back and the blood tests were only done last week after chasing for this to happen . I have requested FNB through the online app to add my kids as beneficiaries this hasn't be done , i have written emails to my private banker by the name of Agnesia to assist she is not responding. I have called FNB LIFE on *** without any luck than tried *** which seems to be the funeral cover centre of which they keep transferring me to which never goes through. I am calling everyday for the past three weeks. This is really frustrating as now i cant add any beneficiaries to the cover should i die my kids wont be able to claim from the cover. FNB should stick to banking they really bad at this, even the banking is disappointing my dad of the age of 76 has had unknown debit orders going of his account in April this year he was hospitalised at the time and my sisters and i tried to track the matter with the bank for week but failed . The debit orders were over R30.000 till this day he has not recovered all the money some were paid but not all. Last year e-wallets were send from his bank account at midnight luckily we were all awake and with him and were able to all the bank and freeze his accounts and retrieve the funds.
