Hey I got a call from Supportonclick.com guys few days back. Asked me if my computer was running slow. I was being nagged by my computer's speed. I said yes. The guy was quite helpful and sorted out the problem in a few minutes. My machine has speeded up considerably now.
No idea about others, but I am impressed by the Supportonclick service. And I don't get one thing, if they offer quality service in return of money, how can they be regarded as scammers? they are not charging us for nothing.
