the indian accented guy said his name is cyan and calling from Tiger Direct regarding my account, did do business on retail level with them. But I google and cannot find any REAL link that claims that they are really from Tiger Direct in any listing, only some 'self-submitted' places said it might be tiger direct.
Didn't sound legit at first, since the guy asked me for update on my email adress and info, so I was very suspicious. But they contact business customers this way to have a single-person contact in the company.
So even if they give an 1-866 number to call back, it's a genuine Tiger Direct sales person.
