******** billing

<p>I have to say im shocked at the way they conduct business!I have been with tracker for 3 years until I received a message from them saying that my unit is faulty and that it would have to be changed free of charge.I agreed on the request to my surprise I got a invoice from them for R1400 for the instalation so I called them immediately and cancelled the service with them.But until now they keep bugging and insist I pay the invoice.I have spoken to them numerous times,then they always promise that a manager will call back,but i am still waiting.They have now sent the invoice to debt collectors,what for I dont know!This is ******ion if u ask me.Who in theyre right mind will pay this invoice?After they sent me emails saying it is free of charge!Please if anyone has advice.</p>
