Tracker Connect-worse service ever

Worse experience ever, bought a new vehicle and requested to cancel/transfer the old vehicle and add the new vehicle. On the 11/04/24 I phoned tracker and spoke to numerous agents regarding the cancelation of old vehicle and fitment of a new unit and adding on the new vehicle to my profile. Yesterday 24/04/24 I phone tracker again, regarding the cancelation (as the old vehicle still shows on app) and an even more alarming issue, new vehicle tracker unit shows that it's at "tracker production site". After speaking to numerous agents again and +30 min later on the phone, they say the cancelation is sorted and that I will recieve an sms to verify that a technician will come and check the unit. Today 25/04/25, still no sms and I call tracker again, 30min later on the phone, the agent tells me that the old vehicles contract was never canceled/transfed and no technician was booked to come and check the new vehicle unit. The agent then told me that she will email the original agent who were responsible to cancel/ transfer the old unit and again tried to book a technician to come and check the new vehicle unit,which they cannot confirm when. Hopefully this will be resolved.
