So scared n disappointed

I am so scared.I wont even sleep tonight.Yesterday the 17 September 2019.A technician came at around 15:15 to fit my tracking device.He insisted I stand with him while he works.We chit chatted.He worked then left.Today the 18 Sept 2019.I saw a guy that meets his description in a private car close to mine.We stopped at the same time at the traffic robot.I called Cartrack three times spoke to three different people who could not locate my car or the device.At the current state that South Africa is in I can not stop myself from thinking the worst.What if this guy is now following me.What if I just sat and relaxed “ thinking my car is being watched”.Tomorrow morning I am going to report this matter to the police and no longer need Cartrack’s service.
