Finchoice fix your system

It is hell dealing with Finchoice. Why is an eft not good enough. I was assured of it having no impact. Only later to be told my account will be in arrears until the next debit order. Always blaming the system. If the system doesnt work fix ir change your system. How can payment be made and you still in arrears. It doesnt make sense. How is this a legal financial institution. Is it your goal to have dissatisfied clients.
