Bad experience

Netstar tracking is a ****, when i got their tracking device last year i was sent the documents confirming the policy and the monthly payment, at that time they didn't deduct my account direct but through insurance. i then told them i left that insurer can they deduct direct from me to my surprise now the amount went up. I'm paying double. when they deducted last month i paid 4 times the amount I was told I'm going to pay from the policy that was sent to me. very disappointed i tried giving them a call being transfered with no luck.
