Poor service delivered

So disappointed with tracker product. The unit in my car was not tracking for 3 days and I received an email notification I phoned them they said I will get a call with 72 hours. I received a call more than 72 hours and had to wait for the technician to come for about 48 hours in the meantime I am driving the car what if anything happened to the car? The technician came and said he just needed to reset the unit which he apparently did and he worked for few hours only. They sent me an email again on friday to say that not tracking happened In the last 3 days after it was fixed on Monday. I was on call and only saw the email on Saturday. Upset I phoned tracker and I have to wait 3 working days plus I don't know how many more days before the technician comes. The bottom line is I think they don't have a sense of emergency. I am paying for me to have the car tracked so for this month about half of it is not covered as I drive the car every single day. The other unhappy thing is I asked them to unify my two profil for my two cars and it was done according to them. I am not able to see my 2 cars on their app. What kind of service to customer is this? I am getting out for a better service provider
