Tracker help themselves to my money *******ly

Tracker *******ly debited my bank account over R3,300 in one day plus the subscription of R119. Refused to refund amount immediately, and even failed to refund it within their promised 7 days. They kept the money for over 2 months, and refused to pay me my discretionary interest. I can charge any interest for money ****** out of my bank account by a corporation. Tracker has now gone silent even after I gave them grace period to pay interest charged. Tracker stole my money. At best, they loaned themselves my money for over 2 months without my consent. Am about to take legal action cause I feel abused and violated.
