*****ulent activities on my funeral cover with Standard Bank

I added my sibling to an existing funeral cover I have with Standard Bank yesterday(21 August 2024) and this is when I learnt that there is a spouse and 2 children who are not mine that are added to my funeral cover without my consent and I am unmarried and never been. Also, my premium goes up every year and I was informed that my cover remains the same amount, even though the premium goes up, is this even ethical???I spoke to Standard Bank employee yesterday by the name of Mangane who took down my contact details and said that the division will make contact with me yesterday still and they never did up to now. I would definitely not recommend their services.
