Incorrectly billing

I am so dissapoint at the level of service rendered by Sanlam , I have a life cover policy that I have been paying monthly as usually , when I made a payment for December I got an email back that insufficient funds and I went online to double check if did it perhaps increased and to find out that it still the same and put in an enquiry with my adviser who works for Sanlam , she logged a query as she also not sure why Danlam wants me to pay double the amount in December .to my suprise no one at Danlam is able to give me answers as to why do I have to pay double in December where else there’s no month that I didn’t pay ..

I have been logging queries with them with no one calling me or explaining why is my premium for December insufficient. This means should anything happen between me and my husband my policy is not up to date .

Sanlam are ******* and want us to pay double the amount with no reasons .

I am considering another service provider for both my life covers for my self and my husband and moving my retirement to another insurance company
