Pathetic Service on New installation

a tracker was installed on my car yesterday 19/12/2024 in the afternoon. i checked on Cartrack App if the tracker was working correctly later that night at around 22:00. i saw the car speed was 1km/hr moving, according to the tracker. i quickly rushed to check in the garage, there was no one in the car and the car was OFF. i called cartrack, they said the unit needed to be re-booted, i must logout of the App and the car needs to be driven for about 10km activate the tracker, which i did. today i drove the car and parked around 08:00, i checked again on the App later, around 09:20, the car was again moving at 1km/hr and was showing that it was swiched off @09:17, which was not true, i called again to complain about this, i spoke to Tshepiso(good service), was told that they need to re-boot the unit again and i needed to drive again about 10km to activate the unit and i did. i parked the car at 10:15, waited in the car for about 15min, checked on App again and the car was still moving at 1km/hr but sitched off ignition at 10:27, very weird!!! i called Cartrack again and i spoke to a very rude lady called Rebecca, she was shouting and screaming before i even told her my issue!!! i asked to speak to her manager but she insisted on transfering me to the "relevant department" the call was transferred again and i spoke to lady called Lerato Matlala(very good service) she told me the unit needs to be repaired and they need to schedule a repair. i requested the repair be done today 20/12/2024 and requested to speak to the manager, i was transfered to the scheduling Department manager and the manager never picked the call. i am helpless right now!!!
