Worst and most pathetic customer service.

I had an account passed over to them. They called me to set up a recurring payment. This was done and I was advised that the account had a final debit in June 2018. Since June 2018 I have called and tried following up for a paid up letter. I was passed from pillar to post to get this letter. Until today no one has helped me. Yesterday I got a call that my account is being handed over for a judgment to be put against my name. And still no one is able to assist me. Now I'm being terrorized for an account it settled.
