Account paid up yet still being harassed!!!!

After writing a review in 2016 about finchoice and having them reimburse me R7000 for debuting my account when my account was paid up they have now handed the same, paid up account over to attorneys. How is it possible that an account is paid in full in 2015 yet in 2018 you hand it over again. I'm so sick and tired of Finchoice playing with my credit record and wasting my time with their incompetence. I have been waiting for someone in their legal department to sort this out for nearly three weeks now and nothing has been done. In the mean time I am being harassed by their attorneys for something that they sent me a paid up letter for YEARS AGO. The service is shocking and how they treat their customers is disgusting. Legal action should be taken against them!
