Four months ago changed a laptop failing hdd and give it back to customer. Today I got a 30 minutes call because the computer "is not like before the repair, it doesn't work well".

*Thinks* Well, s#*@, before the repair the hdd had more than 2000 damaged clusters, which prevented even the os to start

*Says* "Could you describe me the issue?"
....
...
[ basically he was saying that since he started using IE as a browser, he didn't have Google.com set as the first page and that he had to bing it]
...
"When did the 'issue' start, If I may ask?"

>"Two weeks ago. "

Two weeks ago.
Two f*""#ng weeks ago.
Set aside for the nature of the issue, you blame my four months ago repair for a two weeks ago issue?
"The computer was better before"?
THAT F###ING MACHINE WAS LIKE A BURNING HOUSE - I RESCUED DATA FOR 2 DAYS JUST BEFORE THE HDD STARTED TO CRANK AT EVERY SPIN - I REBUILT IT TO GIVE IT YOU BACK FULLY WORKING AFTER YOU USED AS A FOOTBALL, AND NOW YOU BLAME ME BECAUSE THE
BROWSER ISN'T SETTED AS YOU LIKE

No,seriously, is like I rebuilt a burned house from scrap and now the owner blames me because in the kitchen sink the hot water tap is on the right side instead of the left side.
Seriusly, wtf.

Scary sysadmin is scary
