Extremely disappointing!

I have been paying for 30 months, now I wanted to transfer the tracker to a new vehicle, and they promised that this would be done in 2 days, today is the 4th day, no call whatsoever! The new car l have now cannot be covered for theft and hijacking because of its value if it does not have a tracker! I have been calling, and am always transferred to another department! I am extremely unhappy, and the high risk of driving a brand new car with no tracker! So disappointed! The tracker has not even been removed from the old vehicle!!
