Poor

I had a contract with Mix Telematix and when I decided to sell my car I informed them and requested that they cancel it. the device was never cancelled. they kept telling me that I owe them and eventually handed my account over. I handed over all the proof that showed I requested for the cancellation. I then started to receive calls demanding the payment and my name was blacklisted. I tried reaching out to their offices but I was transferred from pillar to post. I eventually decided to pay that amount they wanted and asked them to remove my name. Now they have stopped harassing me but they don't want to remove or clear my name.
