SHADY BUSINESS PRACTICES

I have called the call centre more that FIVE times in a week. I am requesting that my debit order be cancelled which I did NOT authorize. I have NEVER paid DA via debit order (in 3 years +) Always deposit into FNB linked account in my profile. I also wanted to request a statement to see what my settlement is. I have spoken to 5+ people and ALL THE TIME I get a different response or the calls dropped or you are made to hold for more than 30 minutes at a go with no one returning to you (hoping you will be exasperated and hang up). I have spent more than 2 hours on calls trying to get my debit order cancelled (I'm ahead with my payments) and a statement emailed. So so simple .. why is it such a task to do? I regret why I took the loan with them. There is something shady in the way they operate.
