Bad service from cartrack

2021 my account was in arrears and blacklisted. I settled the arrears and received a paid up letter from car track. One of their agents called me after and asked if I would like to reinstate my account and I agreed as I had settled the arrears. My account as been up to date till this day after reinstating my account with cartrack. 4 years later I call in to check if my unit is working and I'm being told that my account is blacklisted and arrears and I asked how and I'm told I was once blacklisted by cartrack in 2021 and the flag is still there. So now my question if I'm blacklisted by cartrack and my account is suspended why is cartrack debiting my account every month and. There was no communication from cartrack about this blacklisting for the past 4 years. I once had a debit order issue and agents from cartrack were on my case calling me everyday and sending emails telling me my account is in arrears by one month yet non of them picked up that there was a flag that I'm blacklisted from agents in customer service to agents in accounts department. If I had called in because my car was ****** was this the BS I was going to get that my account is in arrears and they cannot locate my car yet my account is debited every month.
