Irritating, *********** brand

I have been with this tracking company since buying my 1st car in 2008, never have I had any payment issues until sometime this year when I upgraded my system and some *********** billing individual billed be more than double what I had to pay, since then my life has experienced all kind of bulling, unacceptable tantrums and raising of voices over the phone, I don't need such in my life, I also don't need to be called by inexperienced people calling themselves debt collectors, I know how to manage my finances. I just want you guys to know that I have taken a conscious decision to take this matter to the media, I have total confidence in, speak out, checkpoint and carte blanche. I will not be bul**** and harassed by you through phone calls and sms'. I had total confidence in you and don't even believe that you have the capacity to recover my car if it gets ******.
