Out of warranty

To Tracker management,

I received an unexpected call from Tracker yesterday, informing me that there is problem with my tracker unit.

They mentioned to me that my unit is out of warranty and that if Tracker sends a technician it will cost me R500.

Another option is to sign a new three-year contract and Tracker will replaces the unit.

I am very disappointed in Tracker in the way they give a customer two options. It is also very funny that exactly after three years and twelve days my unit now gives problems. I would like to know from Tracker management how it is possible.
