Poor Cartrack services

It has been a year now paying car track for a missing devise of which I was not the cause of it been lost. I made peace with it since they told me that the terms say I am liable for that.

Now a week ago I get a call from cartrack telling me that they will send a technician to come and fix the unit. This according to them, I am not supposed to pay for both the unit and the technician. Which I agreed to.

Surprisingly, today In the process of fixing, the technician tells me that he knows nothing about the payment arrangements, the same cartrack also calls me to tell me that I have to pay.

I don't know if they did this to temper with the case I reported to the national consumer commission.

I plead with cartrack to come and fix the unit for free as per their promise or arrangements.
