Poor service

I purchased a vehicle in August 2021. The vehicle had an existing unit which were in arrears at the by the previous owner. I requested for Cartrack to initiate a new 36month for myself as I did not want any liability placed upon myself in this regard, neither did I want a transfer of ownership as the previous was not keen on paying the fees. I was told to forward proof of ownership of the vehicle which I had done on a few occasions. Each time I call them back I am taken through the same process of where they need to contact the previous owner for consent then call me back but this never happens. Keep in mind the previous is willing to have the existing device and installed in his new vehicle and I want a new unit/new contract. But it seem as if your business do not have a process in place to deal with this kind of situations or do you just not have any interest in acquiring new business ???
