Worst Service and insurance ever

Hi<br> <br> I have change to Discovery Insure at the beginning of Sept. Worst discussion ever. They promised me cash back and showed me how great they are. I though well give them a change. It is almost 6 mails and 10 calls later and my DQ tag still does not work. Each time they will come back to me, and then nobody comes back to me. And so at month end I did not receive any cash back because my tag does not work. So i phoned them again saying I did not get any money because of my tag and the said it is my fault that there is something wrong with my tag. and not theirs. So they will try to find the problem and phone me back and here I am still waiting for the phone call. <br> <br> Please help me!!!!!
