Debited our account for 2yrs no service R48,000..

This company EEC WORLDWIDE has been debiting our account for 24+ months for faulty (non operational Machines that was collected by their technician. The contract was signed with WPS Which EEC has taken over ! As our contract was close to expiry,we instructed the technician Lucas Smith to cancel the contract upon expiry. We unfortunately after an audit realized the account was debited for 24+ months after expiry. No communication or contact was made by this company after expiry of the contract.. When I tried to claim my money back 30-01-2014.. I was told Lucas Smith the technician no longer works for EEC.They are not aware of the cancellation on any faulty machines.So EEC Worldwide has taken our money for no service rendered.I have asked them to show me any communication or recorded history of transactions done! Just been ignored and given excuses. They don't keep records!! So I,ve been taken advantage of by a WORLDWIDE COMPANY CALLED Enterprise Electronic Commerce SA Pty Ltd. Will people out their please make contact with me that has the same issue.. I am going to use every possible option to expose EEC in every way possible. I am not letting down!
