4 months and counting and no feedback

In February 2015 I notified Discovery Insure that my wife's vehicle's DQ Tracker is not functioning properly. Due to Richards Bay not being listing on the automatic booking process the call centre promised to have someone contact me to schedule the appointment. I missed one telephone call and did not have a returning phone number so the only thing to do was to contact the call centre again. Every phone call since has had the same response.. \ someone will phone you.."That someone has never managed to phone me again and it's four months down the road. Who's going to take responsibility if the vehicle is ******??? And how will I be re-imbursed for the Vitalitydrive fuel spend being lost due to no recording of DQ points??? Pathetic!!"""
