Poor service

After 3 months of having in my Tracking unit the back up battery started dying and drained my car battery. I bought a new battery and it still drained, thereafter car track sent someone to replace the unit and it was fine for another 3 months but now it is draining my battery again. I spoke to someone in the CEO department by the name of Kavitha Lalla and she wants me to pay a call out fee for a technician to check and to resolve this problem all I wanted was for them to put the tracking on sleep mode to solve the problem. Right now she is ignoring my emails and when calling, she's always busy. They promise she will call me back but she never does.
