A couple of months ago I had a older brother win a trade in computer at eBay auction some $400 for his 16 year old sister, father wanted pickup as they were only 50 kms away. Father then decided pickup meant delivery. Finally 2 weeks later met father at local PO he was late and no apology, took 30 mins to inspect unit ( tried to bargain down). I found out took 2 weeks as did not have money till centerlink payment.
I had wiped and set up unit with XP as per auction, and brother agreed with me, as older machine would be slow on vista. Got home at 9pm after doing other things with 10 phone messages each getting ruder. To cut a long story short the girl got the unit to connect to family wireless router, but not LAN network with the other 5 computers in the household. She had then wiped Xp and installed vista from manufacturer original disks. Now she could get to LAN network but no wireless.
They wanted me to drive 50kms that night and put XP back on as vista was too slow and get it to network and connect with all her other toys. The family went into melt down mode when I said I do not set up networks as out of my area of expertise. I did recommend someone local closer to them who does setup networks. Charges $80 an hour business hours, workshop / unit / workshop. I also informed them formating and reinstalling Xp is slow it is a $90 charge in mine and his workshops as you do other things while it chugs away. Going to her, for me some $70 travelling time and another $200 while it chugs away in business hours add 50% for 10pm till after midnight . They then got ruder and I informed them I sold them tested and working hardware, not software lessons after hours. They got hysterical I said goodnight and hung up, dad obviously 10 drinks/drugs past sober.
The family and friends hounded me for months on phone and eBay. Till I got some of them banned for spamming and nuisance calls, by eBay and telstra they then disappeared. Typical welfare bludgers the lot of them expecting everything for free.
