Tracker vehicle tracking is absolutely hopeless

Updated my personal and contact details with Tracker on the Tracker App and customer service also cancelled my contract for a vehicle sold. Concluded a new contract for a new car updated all my particulars once again. The panic button was activated in the custody of the dealership I sold the vehicle to yes as you guessed Tracker phoned me the contract not cancelled. The Tracker Care installed in my new car. The info on the certificate issued by Tracker differs fundamentally with the information on the certificate issued by the installer. Tracker certificate has my old contact and home details notwithstanding that I updated this. The new car details also incorrect description. After installation I activated the panic button. After four minutes they contacted my wife on the alternate contact number and not me on my current number. When queried Tracker said they contacted me on my old number. Tracker is absolutely hopeless.
