Worst Customer Service Ever

<p>Initially when I got this tracker for my car, I aggreed for them to do a debit order on my account, then after they incorrectly debited my account I cancelled the debit order and started paying them Via EFT, this went fine for over a year, then all of a sudden they put my installment amount up and started doing Debit orders on my account again with out my permission, so in other words they got double payments as I was not aware that the debit orders was going off. When I phoned the customer service the lady who answered was not helpful at all and spoke to me like a child, she also said that they only owe we 0.72 cents. How is this possible if they got two installments this month. I am beyond frustrated and dissapointed in them. I have cancelled my service and I will tell everyone i know to never deal with them!</p>
