Challenge getting Netstar to remove tracker resulting in battery damage

My Netstar tracker has been draining my car battery. I reported it to Netstar numerous times since 14 April 2025, but no one has assisted. The tracker has damaged my battery, requiring a new car battery. Toyota advises that if the tracking unit is not removed, then the new battery will suffer the same issue. I have made payment to get the unit removed, but I still cannot get any help from this company.
