They bury you whilst still alive

I have had a funeral cover for years with old mutual. I was approached by a consultant trying to sell me extra cover and I refused to get extra cover. Then the damn consultant decided to cancel my cover. 2019 til now, I sit thinking I have cover and I am suddenly told that my years' investment is cancelled. How do they kill me when I am still alive. When you send email, you receive automated emails and not calls.
