After about eight calls in a couple of days I rang the local cops, then telstra, then my local member. These guys are using internet calling and thus unable to be blocked.
So if I can't stop them, it is time to have some fun. This is my list of techniques so far.
My favourite is to put on the creepy voice and tell them I am naked and ask them what they are wearing?
Pretend that I am a member of the AFP and ask them to hold on why I set a trace going.
Pretend to have a heart attack and ask them to get help. They never do, but it plays on their mind.
Put them onto one of the kids to get told of all sort of crap.
Fart and burp into the phone - yeah, I am a bloke.
If they are male, ask them if they have a single sister or if they are female, a single brother.
Try to convert them to a religion.
See if they want sell one of their kidneys or eyes.
Play along but swear continously (not at them but just in general with plenty of Fs and Cs)
Brag about catching a fish or some other rubbish.
Stir the hell out of them about their cricket team's effort in England.
Pretend to be hammered (sometimes I don't have to pretend) and slur and stumble my way along.
Ask them if I can use them as a job application reference from a dole form.
Try to sell them drugs.
Tell them there is a power outage.
But the best came when my dad (75) was visiting and he wanted a go. They went on with their story about being a windows support company and so Dad replies that their assistance would be greatly appreciated. Excited that they have finally snarred one, dad goes on trying to organise a time for them to come. Bemused they question, but he keeps on that Thursday is no good as he has a prostrate exam to be done, but Friday would be good if that works ok with them. Eventually he ask when they will be coming over and they say they can do it remotely by just talking him through it. He responds that he already knows how to service his windows but as he is too old now they are getting dirty and too high for him to reach, so needs them to service them. They try to explain, but he keeps on at them until eventually they give up and hang up. It was awesome to watch and listen (via speaker) him at work. What is the saying - old age and cunning wins everytime
