Debit order Nightmare

I have been trying to set up my debit order for my Edgar’s account for the last year and a half. My account has time and time and time again been in arrears since it opened (without my knowledge, I had been in possession of this account for over 1 year before I knew I had it, but that’s another complaint). I attempted to set up my debit order over 4 times and given the same response that my account needs to be up to date for the debit order to commence every time I have made it up to date and every time it does not commence putting me arrears every two months, and get this Edgar’s only notifies me after 2 months, this stupid account is affecting my credit score. I am tired of this, I just need the debit order sorted so the account can be paid and I can close it . I am done with Edgars and it’s dodgey money making scheme.
