Poor customer service

I'm so disappointed with the service I'm getting from Absalife. Almost 3 months trying to get service from them with no success. I've been sending new banking details to them and getting confirmation that my details are updated. November and December debit orders are still not presented to my bank. I took the initiative to let them know that debit orders are not presented, to date nothing is done next I will be told my policy lapsed. What is.it that I need to do to get debit orders presented to my bank?
