frustrated with Dove, I need answers.

I received, a SMS regarding dove changing their underwriter from 3sixty to "dove group holding", and they put me through to 3sixty, but the call was disconnected, and I am not getting through to 3sixty life, been holding on now for a while, they don't even have answers because it's not the first time dove change underwriters, so why do I have to be the one cancelling 3sixty life and not them moving the policy?, now I see DGH tried to debit and 3sixty life already debited my account. I am asking them what I need to do now, they can't even answer, their answer was I phone the bank and cancel 3sixty until the policy lapse that was the advice I was given over the phone. why does this have to be my problem now? and "there' nothing they can do on their side" I really don't know where this leaves me now.
