Idiots - chasing me for a non existent debt with Optus neither Optus or Probe staff have authority to investigate to realise that Optus' own correspondence says it is a mistake . Firstly they said they were part of Optus then said they were a independent debt collector . Charging people on 1300number and then putting you on hold for 20 minutes only to speak to noone - hung up . Deplorable Optus should be ashamed. Bad business.
