Paying for something that was never installed!!!

After sending an email 2 days ago and didn't get a response. Let me put this here...

So on 4th September 2018 I decided to test the panic button in my car. I pressed it the first time, no one calls. I pressed it again the second time and guess what, NO CALL FROM CARTRACK.

I immediately called in and guess what the lady told me "They didn't get any signals that's why no one called"... So this actually tells me that this thing never worked, it was never installed. So I've been paying for something for 6 months now and its not working???? I am really not happy about this. What if I needed assistance at that time???

In March 2018 you installed the tracker and the panic button and it was confirmed that everything is in order. Just to find out 6 months later that this thing is not working!!!

I would like you to repair/fix these faults within a week and I would like you to refund my money that I paid for this panic button for the past 6 months that has not been working/installed.

Seems like I'm not the only one complaining about this. So this is what you actually doing to your clients??? Maybe I should consider it to go to another tracker company because this is very *********... If only I knew...
