MY NETSTAR APP FRUSTRATION AND ABSOLUTE USELESS

installed updated 2 units in vehicle. first only "gsm error" on app the whole day - reboot system but how iF there is no option. 2 references and issues logged with technical department.NO HELP still waiting for even a phone call. previous system shows my full address on app so when not at home i know my vehicle is safe at my address(i am client now about 10 yrs already). guess what 5th day today & this morning (after uninstall app yesterday to try and see if this fixed the gsm error problem) install app again, jip its now working. this morning it shows my vehicle is standing a block from my address and picking up signal at new address. can you please come and remove your system and install my old one that was working 100% without any issues from day 1, because i do not trust your so called new improved technoly at all. so lekker pay more for less service and problems now for 5 days to hear techinical technical technical department / IT IT IT Department. im done spending money on useless phone calls. unless you can guarantee that my full address is going to show like on old system, im not happy with just a street name. every minute new issues. believe i am not the only 1 complaining about your app not working!
