Debit order change

I'm trying to change the details of the debit order of my life policy to a new contributor/payer.There was a problem with section 3.2 . Each time I would reply and tell them I've updated the form with 3.2 and each time it's a new agent replying asking the same question over and over that I must complete section 3.2 and I would reply that I did complete it and send it through.We are going in circles and getting nowhere.This morning they reply with an email that the form of 25/12/2024 is outdated and must be updated again.This is ridiculous.Each agent has their own story.Can a manager please contact me.I also send in a form for the change of beneficiary.I would like confirmation on that.Please contact me
