Unkept promises causing chaos!!

All their calls are recorded so I have proof that I was promised that my tracking device would be deinstalled and reinstalled from my existing vehicle to my new vehicle today!This is happening today, I will not have the existing vehicle in my possession after today! Now I'm told when I phone to confirm the process for this morning that it will only happen on Tuesday!! This is totally unacceptable, your customer service agent confirmed today as recorded on your system, I cannot drive my vehicle without the device as it is part of my insurance obligation! I am disgusted, I will not pay another provider to install it as their rates are exorbitant! Don't treat your customers like this. Why am I paying you a monthly amount for something I now won't have?!?
