Failure to debit on the requested date.

You are going to lose a customer because you are failing to action a debit order change as per my request. I will move my policy to another service provider if you continue to fail to action such a simple request. You insist on debiting my premium on the 25th while I have explained twice already that I get paid on the 26th due to changes in jobs therefore just move the debit order to the 31st.
