#Be Warned of Tracker Connect

I sold my car in 2020 and immediately canceled Tracker (TRACKER CONNECT PTY LTD) membership for their tracking service with effect from 30/11/2020. I then received the letter to confirm their service cancellation. I was requested to pay a settlement amount of about R293.80 which I did pay on 28/01/2021, and also sent the proof of payment was sent to Tracker. To my surprise, I started receiving many calls from both Tracker and Brooksnuyt.co.za, demanding the amount already paid. I further send them the proof of payment and Brooksnuyt stopped contacting me after several times explaining myself. Now, BOOM, Tracker is trying to transect debit order on our bank account without our permission though I do not have any contract with them. Tracker is now sending me threatening messages, I really regret working with them earlier on, and be warned. It is like I once joined the ******* and am HACKED.
