My mom took out a life policy and I am the premium payer

My mom took out a life policy and I am the premium payer. I have only seen the debit order in October. There has been no attempts thereafter. My mom called and dealt with such a disrespectful consultant that did not want to assist her and even used sarcasm! Eventually when she spoke to someone who was able to assist her they advised that we need to pay an amount of R1400 . Which is absurd! There has been no attempts to debit and it is not a fault of mine . Discovery knows nothing about the CX code
