Kept paying for a faulty unit

Good Morning

Hope you are having a good day because it's about to get a whole lot worse.

I called the cartrack call center yesterday to change my address as I moved from PTA to JHB recently. But to my surprise, they told me that my tracking unit was faulty. Not only that but also that it has stopped working in May, and Cartrack was reluctant to inform me of this.

This means that I, the naive loyal client, have been paying for a BROKEN unit for the last SEVEN months. Needless to say, I am absolutely furious. What I want to know is how what you are going to do to justify this? Are you going to either reimburse me the R1 113 you STOLE from me, are you going to upgrade me to a better unit free of charge at the same monthly premium, or am I going to withhold payment for the next seven months?

Not so kind regards

Dave
