Terrible service with Cartrack, try other tracking companies

CARTRACK have been dediting my account on the 15th and on the 22 and on the first of the month , different amount and when I enquired I got this lady called Lindsey Berenge, she couldnt give me a proper explanation. Can you help why? I mean if you are looking for tracking divice donot consider CARTRACK i think due to the amount of customers they have they grew wings and arrogant and they are not willing to fix their mess
