Need training for customer service

When i took my policy i did mention that debit order must go through on the 25th last month it went on the 30th this month i get message that says if if that debit order is not paid your cover will stop , and if they can go through calls recording and check the last time when i called i was told that my debit will go on the 25th its been fixed on system i didn't even ask for call ref as i thought i was talking to people who know what they doing i been with Hollard from 2003 and i really don't appreciate all this now i must pay 150 for every debit order that go through before my salary get transferred and the lady i spoke to she has a very bad attitude and keeps on arguing with me like she have shares with hollard or she own the company
