Tracker - worse service

It been almost a week since I relayed my complain about the monthly billing. No one from Tracker service department has contacted me to engage with me on my billing and I spoke to a Consultant early January to remove all of these unncessary errors on my account. Now Relebohile Shikwambana sends me an email stating that my additiona billing is for insurance and subscirption....why must I be paying addiitonal subscription for Tracker and also insurance because I already have car insurance. What fustrate me with Tracker is they dont contact the customer to clear a query...u try to call them you cnt get through
