Tracking Device Noit Working

I logged on to the Discovery website and clicked on the DQ Mapper link. A message came up that my tracking device could not be found and that I should phone Discovery. I was told by Chante that it seems that my tracking device was faulty since September 2015. I then told Chante that this was not acceptable. I was then transferred to Ashley who told me that I was notified via e-mail of my device being faulty and that I had to phone Discovery to have the problem resolved. I feel that the responsibility lies with Discovery to contact a client when a tracking device is faulty, not the other way around. Don't hide behind e-mails and when the client do not respond leave the problem, have the courtesy to pick up the phone and notify me in person. Although my vehicle was insured, despite the fact that device was not working, I lost DQ Points. I pay excessive high premiums on this policy, but never had a claim. I recently changed my risk address, why did the call centre agent not inform me of the faulty device while changing me address?? Obviously I'm not important enough for Discovery, just my ridiculous R2000 premium every month!!
