lies lies lies

My husband tried to cancel our contract not realising we had signed a 36 month contract of which they told us we have 10 months left so my husband told them to leave it on Because we not going to pay the cancellation fees then they said we can pay r99 a month and for and additional r25 a month we get insurance for the tracker but my husband decided against it and now 2 days later all of a sudden they say our tracker is faulty and we must pay r1400 to repair it ????? Who has that kind of money just lying around ,Plus they can only tell you in 72 hours where your car is , so what are we actually paying for ? It's just another money making scheme
