Cartrack won't listen to my customer complain

Had a tracker fitted on my car,which I used for Bolt as an income and is now mechanically beyond repair,yes I know of the cancellation fee, but now my issues is I explained that I won't afford the debits/ the cancellation fee as I do not have an income anymore... I even told the call center agents that the mangers or board of directors can override the contract by cancelling fees as I have no means anymore,but they not willing to help me?
