Bad Customer service (****)

In November 2019 I took a funeral policy with B3, T's & C's were explained I was happy to take the cover. 2020 they decide to change underwriter and without any formal communication, premiums went up. Again in 2021 they change underwriter again without any formal communication and premiums increasing again now from R514 to R693 and they said something about benefits reduction. I've been trying to contact them, even today nothing. I don't what is going, I can't get hold of the consultant or even their complains department.
