They play dumb when you want to cancel an account

I bought a new vehicle and have requested tracker to transfer the old account or unit to the new vehicle. Oh my goodness that sounds like rocket science to them as I am still waiting for them to do that for 2 weeks now, I had to let the other vehicle go with the old unit because they were not willing to assist. I will have to cancel all the accounts I have with them for my other vehicle s if they charge me for their incompetence.
