Poor Customer Support - Reinstallation of Tracker

I'm in the process of trading in my vehicle for another, and simply need to disable the device in my current (old) vehicle in order to do a new fitment in the new vehicle.

I've called in twice, both times the agents confirmed they'd just follow up with the technical team, to give me a callback, and it's been 2 days now with no follow up made. The communications between customer support and the technical team seem to be pretty broken.
