Incorrect member removed and been paying for late member for 2yrs

Last month my uncle past away and I called old mutual as I had covered him. To my shock my uncle was not appearing on my policy schedule. What I suspect happened what happened in 2018 was that I request for another member to be removed and it turns out that the member I nominated to be removed was not removed and instead another was removed. Right now both these members are deceased and I have been paying for the “removed” member for the past two years. Meanwhile my debit order has been going off never once lapsed. I’ve sent numerous Emails to their claims department no response and worse part is calling you hold for over 30min only for their *********** employees to hang up in your ear or put u on hold indefinitely. I subsequently went to a branch in Greenstone and 2 weeks later I have no traction nothing from Jerome.
