Arrears interest charged on up to date account

Good day,

I am highly irritated with your company.

I received my statement, for an account I have with you. To my shock, it seems I've been charged interest on arrears, however, the account is paid via debit order. How the **** am I being charged interest on arrears, if the account is not in arrears.

I phoned the call center, to try to get clarity, but behold, you have the wrong contact number on the system. Now I need to go into the bank, to get this sorted before you can this sorted.

I do not know where you got the incorrect contact details, but I am for sure not going into a branch to fix your mess. I want the interest you deducted due to an incorrect arrears charge credited to my account, as I was never in arrears to start with. This is *****ing, plain and simple.

I am going to escalate further if I do not have any communication from your company in the next 24 hours.
