Netstar just does not care.

I called Netstar on 22 June to request a cancellation of my tracking device service on my vehicle from 30 June, as I found a better offer with an alternative service provider. I was then advised by their agent that I should rather call in on the 30th of June, as this it would be best to cancel on the last day the service was required. I then did so and called them on 30 June to request cancellation, and was then advised by Kabelo that I will need to pay a settlement fee of more than R800, as I was still in my 36 month contract period. I then expressed by dissatisfaction, as would have preferred hearing about this on the 22nd, as I already had my new service provider's tracker installed on 29 June, as I was still in a position to cancel this much, had I been aware of the contractual obligation. I was told by Kabelo that he would escalate my complaint to his supervisor and they would call me shortly to discuss. I then called Netstar the next day on 1 July and spoke to Nicola, who then advised that the escalation was sent to Stacey and that she would also follow up with Stacey to call me back ASAP. I have still not received a call from Netstar, as they obviously not value their customer complaints and treat it with the necessary attention, bearing that today is the 12th of July. I wonder if I would be lucky enough to get a call from them now, after having to go this route of exposing their uncaring nature.
