Metropolitan claims that a retirement annuity is null and void when you die

Metropolitan has been audacious enough to send us from pillar to post regarding my late aunts annuity which she was paying religiously till her death in August 2025. Their last deduction was in July. My father was given power of authority for all her assets and he was then made beneficiary as she had no children / siblings as per the required rules by the trustee. The Westgate branch sent us to the Head office in Johannesburg where a consultant told my father that when a client passes on - they pass on with their annuity. The insult on our intelligence merely because you do not want to do your jobs? Why were you still deducting money from an 81 year old? Your consultant even had the nerve to say we have buried her already so what more do we want? At what cost? Your employees that represent your statutes are a disgrace, because according to the Pension Funds Act section 37C there is no requirement annuity that lapses when you die without a payment, the funds become payable as a death benefit. So kindly tell us as the consumers are you running a ****? Do we pay you to refuse with our money? Is that even legal?
