Please help , i am at my wits end trying to cancel

Two months into having tracker installed on a new vehicle I decided to cancel the service. I am now being penalised with hefty fines which I cannot afford. I have been a client for many years and had a tracker on my other vehicle. To be entirely honest i was not fully aware that i was entering into a 3 year contract and each time I call I am read the terms of this contract.<br> <br> I feel so hurt and insulted as a loyal client. Please help me end this nightmare.
