Cancelation

I had a tracker unit installed in my vehicle a few years ago when I bought my car in 2016/17. I then decided to cancel the contract as I was no longer interested in doing business with tracker. I then received a phone call from their cancelation desk where a lady consultant assisted. I it is now close to a year later after canceling where I'm now being told that my account is still active and was never canceled and I now owe Tracker money. I then requested the attorney company which called me to request for the phone call records which in my knowledge need to be kept but no one is coming back to me. On 04/01/2021 08:00 I received another phone call from the same attorneys probably 4-5 months from their last call telling me I'm in areas. Clearly the last request was never forwarded, the only evidence I have is that recording on the day of the cancelation where I was told confirmation of the cancelation would be sent via email, till this day nothing has been done. Clearly the phone call records have been tempered with because the company does not want to go back to that recording. I requestted to be contacted using their website where a consultant then called back but it's clear that my cancelation was never done even though on the call it was confirmed. I need to have this resolved as soon as possible.
