****** vehicle,,,no communication

We bought a vehicle and it had a tracker under the previous owner's contract,the previous owner 's acc was in arrears.The vehicle got ****** on 12th/03/2015,and the previous owner reported a ****** vehicle to car track.He was instructed to settle the amount in arrears sothat the vehicle can be recovered.Out of desperation we settled this acc and sent proof of payment on the same day the 12th.Ever since settling the acc we have not received any communication from cartrack regarding progress,,,we phone them everyday and they tell us they are still unlocking the unit cos it was hardlocked.Really can it take the whole week to unlock the unit.Why were we given empty promises that the vehicle will be recovered once payment was made.This is poor service at its best.Should they recover the vehicle i doubt if it wil still be complete.They caused unnecessary delay and they dont bother informing us about the progress
