Pathetic service

Worst service ever- I have an issue with the device installed on my vehicle which car track told me it is faulty and it affects the ignition, the vehicle constantly switches off and apparently it drains the battery of the vehicle, at first I was told to take the vehicle to Randburg on the 25-07-2022, I was told all is well, on the 28-07-2022 the fault started again as nothing much was done the guy by the name of Israel came to check the vehicle he assured all is well but I still had issues, I took the vehicle back to the dealership, they asked the technician to come and and inspect the vehicle but no one is available, I called car track this morning and I was told a technician will be available next week Wednesday on the 10-08.I have to wait that long before the faulty device get checked
