As Maxwell Smart used to say "Missed. . . by that much". Great post, beat me to it, & glad you put it up.

I am not concerned about who they are but I got my computer fixed in affordable price.I didn't provided them any of my card details and they didn't asked me to do so . I'm happy with the service..

Scammers!!!  Do not allow them into your computer unless you want to pay a huge fee to get it back!!!

Sure you are - you must work for them - this is a well known scam.  And if it isn't, then do feel free to give us the legal company name, verifiable street address and website, if any.  You won't because it's a S-C-A-M!
