Accounts department

Last month I had called car track to check if my device is up to date and has no glitches, only to be told that my account is in arrears and I can't be helped. The 1st call I made was on the 28th of July, literally called I after I remembered that the debit order went off. I was transfered to the accounts department and the lady I spoke to said I'm being blacklisted but is also puzzled because my account is up to date. Said she'll escalate the matter and give me a call back the following day which she never did. I've been calling in every week of August without any assistance. The last lady I spoke to which was last week said I was blacklisted because I missed payment I told her yes I remember the incident and I fully paid the money I was in arrears for but I wasn't informed that I'm being blacklisted. What's painful is I'm busy paying for a device that's in my car that I can't even get access to and not protecting my car.. I took a different package sometime last year in 2022 and I still wasn't informed about being blacklisted.. if I was well informed about this I wouldn't be calling 1 year and couples of months later asking What's going on... I need assistance or just cancel my relationship with cartrack
