Tracker poor service and response

I Bought a Mahindra from Mahindra east rand. I took delivery of the vehicle on the 14th May 2022. on Monday the 16th I get an sms and email that I must please advise if I am using the car. I phoned them and told them that the car is in daily use. They said they need to send out an technician as the tracker is inactive. But if the problem is not the tracker I will have to pay R597 for the call out. How idiotic! I have the car 2 days and the tracker is not working. I requested them top come and remove the tracker. I am still waiting! Today 23rd May my phone rings wow it is tracker from tel no *** just want to confirm the car is moving and in use as the tracker is unresponsive! I again asked them to come and remove the tracker and still no joy. They want to talk cancellation clauses etc. etc. How the hell can you charge me a cancellation fee is the damn thing has not been working!!! You product is any case faulty and means nothing! All i want is to have this ******* removed form my car to enable me to install something that actually works!!!!
