Bad services really Car Track

I have a payment arrangement in place with car track I pay them through eft my balance I own them is about R756 my services on App was active now they suspended my services and demanded the full pay. As I told the respect my financial circumstances. I have arrangement to pay R600 every month but they call me every day. I am very disappointed really even tell when ever something happened to my vehicle I will be held accountable to pay them R25k to dispatch there car track agent out. But I am a Christian nothing Will happen to my vehicle. Thank.
