Money for nothing and your car is where...?

So for quite some time now (probably two years if I were to thumb-suck) I have been calling Netstar every couple months to ask them to test my device. In all honesty I can't remember the last time they could tell me where my car is. I'd always go through basically the same conversation with them: Agent: "The system is hanging/taking long to respond. I will call you back once your device has responded" Me: "Is this normal? Seems strange if you can't find my car immediately..." Agent: "This happens sometimes. Sometimes the system is slow. I will call you back"

I would then proceed with the rest of my day, I'd forget that they haven't called me back and a couple weeks or months would go by and I would never hear back from Netstar.

Last year end of November I got fed up with them and demanded an explanation. Now it's come out that my device is probably malfunctioning. So due to all the cat-and-mouse they forced me to play I immediately demanded a cancellation of the services. At this point their retentions agent that I was dealing with (Hamilton Theka) would stop responding to my emails... From November the 30th to February the 13th I heard nothing back after emailing Hamilton no less than 7 times asking what is going on... Needless to say during all of this Netstar continued to debit me every month irrespective of my request to cancel.

On February the 14th I called them again and ended up finding my way through their call center back to Hamilton and I got some ******* story about how he no longer had any of my emails so couldn't get back to me or whatever.

I was then promised that the cancellation would be put in place and I would be refunded for all my months of non-service. So far it looks like the cancellation has finally been put in place (The month is still young, so I'm keeping an eye on things at least until the end of the week to see if I get debited or not), but now Hamilton has commenced radio-silence all over again about the refund I was promised.

After being with Netstar and paying them without fail since at least 2012 it is very disappointing that this is actually their below level of ethics and professionalism that they proudly display.

I honestly do wonder if they could ever tell me where my car ever was since day #1 as I highly doubt they ever had such fancy technology/s****s at their disposal and ever will.
