Flemix and Associate Inc trying to rob people.

this is regarding the garnish i had with Flemix and associates. money was going out from my salary for 2 years and it stopped in December because i was done with it, now i'm calling them asking for my Paid up letter and they are telling me that i still owe them R14000.00 and more. i never stopped the garnish and my salaries department said it was paid up that is why it stopped. Just had a chat with my salaries department regarding this garnish and they said it's done but when i call your department(Flemix and associate they say i still owe R14000.00. How is that possible because my salaries department say everything is done. i am not happy with the service i'm getting from Flemix and Associate. They are robbing people. When i asked to speak to the manager i was put on hold for a min then told she's Tea just because i was looking for more assistances.
