I think you can see the funny side from the way you wrote  the post, so I hope you don't mind me saying that you gave me a laugh describing the calls!

Yeah it is kind of weird, I cringe that he is calling me again but kind of have a laugh telling people about it afterwards..  

I should have just bought the machine off you.  ... ....

Sticking with other collectors may be safer, I certainly won't bother with gumtree next time, it seems to attract a certain type, heard a few horror stories recently..

Next time get him to call 1800 333 555 (Lifeline-someone who might care) lol  

Well I did send him the 'let me google that for you' link in the end as I like that is says "was that so hard?" at the end  

I don't like being outright rude to people asking for help but I am going to have to be with this guy as he is just taking advantage..
