If ANYONE called me randomly on the telephone, without an invite by me, and said they had intimate knowledge of my computer ("was desperately in need of attention"), I'd be sure to immediately hang up.. It's clearly a scam and my next call would be to the police, giving them as much information about the call as I could come up with..
Clearly, no one, but myself, knows about my computer and its generally functioning, especially some unknown caller on the phone...
Oh well, sounds like the old saying "live and learn" works here.
Hope this helps.

I received a telephone call from CEYLON INFO-TECH that my computer was desperately in need of attention. They in turn advised me of what this would entail, and after discussing the initial cost levels, I agreed on their charge of $79.99 for a one-time work-over (I owned and ran a custom computer design, assembly and configuration business from 1989 to 2000 and I wanted to observe their approach and level of expertise).
CEYLON INFO-TECH to proceeded to take over access to my laptop online and begin hesitantly "fiddling" (note that absence of the words "technical" or "repair") with my machine, which I observed on the screen as they worked. Their employee (certainly no technician) carried out some sort of indecisive muddling with files and directories and, as a result, my was computer turned from a one year old happily customized WIN7 desktop-replacement-level laptop to a flat plastic doorstop.
Yup, CEYLON INFO-TECH managed to effectively destroy my PC's functionality in about half an hour!
Bravo, CEYLON INFO-TECH!
My five year old kid would need adult guidance and over an hour to do what your CEYLON INFO-TECH service guy (please, this was no "tech") managed to do in less than thirty minutes. That's right - my
laptop would no longer boot up, nor could the online CEYLON INFO-TECH employee (once again, no "tech") repair the damage he had done!
Ultimately I was told to re-install WIN7 from scratch. Goodbye to six gigs of pix, data and a year software customization!
Yes, my bad was not backing up my computer. But, then, WIN7 has proved to be a dependable operating system and Toshiba makes a solid product, so I was not apprehensive and I figured that a company
with an strong online presence would be competent - WRONG!!!
BTW, CEYLON INFO-TECH refused to refund the $79.99!
"Our technician worked on your computer for about half an hour and it should be running much better now." And, oh yeah, "We will not refund
your money"
In the end, a word to the wise: if a call from CEYLON INFO-TECH arrives at your phone, just say "NO THANK YOU" and hang up! SAVE YOURSELF!
But, of course, maybe you are in favor of personally supporting online liars and thieves!
