Untrust worthy shark of a company

We have been struggling with tracker from 13 April our Mahindra was written of by a taxi in Rosslyn.I called tracker to ask them about this device that was in the vehicle. If I cancel the Contract there will be a a contract breech fine pay bill to them. I asked him why should I pay for something that I don't use he said it was a binding verbal agreement .when we get a new vehicle the contract would be transfered to the new vehicle,then they came with this story that we have to pay over a R 1000 for a new unit, my husband asked why it's not my fault that the other one was damaged he told them that he can not afford that he is a pensioner she came back to him said that they going to give him a credit it's still go g to Cost over R500 he told them that it is the max that they can go.He told them that if they force him to pay that it would be in monthly installment until it's payed up. On the 2nd of June they send through a debit order for R 1100 I called them who gave them the permission to do that the was no verbal or any kind of authorisation from our side .one of the consultants said she would , pull the call records still waiting for it ,have lost count of how many consultants I have talked to about this the last one was last week She told me that it will be in the account this week Thuesday it's just bank to bank.it know Thursday still no money I called them she told me that it was allocated wrongly to his account at Tracker and not his bank account and it's going to take another 7 to 14 days working day. If We had that R800 to buyout this a contract We would do it today but don't have it.so I hope tracker reads this I warned them I would do it.
