Cartrack

Cartrack service is poor,Im not happy at all . I've got 2 cars and I'm using their services .I sold one car 3 months ago, I've been calling them to cancel the tracker on that car i sold but no one has assisted me yet until today, they keep on saying on of the agent from cancelling department will call 😒 . And they are debiting from my account every month, so this month they didn't get the funds when they debit, now they are expecting me to pay that amount . AND I can't pay for a tracker for the car that i don't have .🤷♂️😓
