Beyond frustration ?

I have never dealt with such incompetence before. I have been battling for 1 years now to sort out my account. I call the helpline and gey told they can't help me I need to send an email, so I email them, to only receive a universal response , I than reply to that email and wait another week for a different staff member to answer me with another universal response, and this has been going on for a year, I can appreciate that things have been challenging however how is it that I need yo explain the problem and solution to someone that is doing this everyday, I just want to resolve my account as this month was the last month for a debit order of which more that than what was needed. How can it be this difficult.
