NO RESPONSE FROM MANAGEMENT

From April 2013, I had a tracker installed and it has never worked, the panic has never worked. I have tried to contact your customer services on numerous occasions throughout the years, but had been pushed from pillar to post without ever getting any help. It is now 2 years later and I have been paying for a device which has never ever worked. I stopped payment via my bank to your account and this is the only time I received ANY correspondence from you guys, which was an sms advising me that payment has not been received.<br> I had previously emailed Elza and Jeremy and received a reply from Elza saying that someone would contact me, but that was - 3 months ago! on 29 April 2015 i received this msg from Elza:\I have asked the correct department to make contact with you. Apologies for the lack in communication."and still today: 6 May 2015"
