Can't get assistance from ABSA

I have a home loan/ bond with Absa. I also have a life policy with Liberty. The life policy was attached to my bond at registration. Now I have changed my life policy and now using FNB. I would like ABSA to update this and confirm so I can cancel the Liberty Life policy. I sent the first email on the 18th of December. I haven't been able to get assistance with updating from any of their departments. Homeloans can't help,Vetting can't help, Absa life can't help and I'm sent from pillar to post. As I write this both policies with Liberty and FNB are active meaning I'm paying even more because both will debit at month end. I don't know what to do because I moved to FNB as I was looking for cheaper insurance
