Yes, they offer a money back guarantee that they won't sell your name, number, email address and job function to others! Unfortunately, since you didn't pay anything to get that 'free' whitepaper, that guarantee is worthless.
They have called twice in the past two weeks, the first time I transferred them to voicemail, and the second time I let them through to our IT department and let them handle it. When I inquired later if I should request DNC for this number, they said they had actually received information from a tech vendor they were looking into. The calls have since stopped. Looks like they're just trying to send out some useful info to techies.
Just got a call to my direct in number at work. The caller's foreign (probably Indian or similar) accent was so heavy I couldn't understand much more than something about white paper, this is not a sales call, and it will only take a few minutes. I didn't see much point in going on even to find out what she wanted if I couldn't understand her.
Female caller who sounded as if she was high. Asked for someone who does not work here and when I told her there was no one by that name she just said "OOOOOOKKKKKKAAAAAAYYYYYY!" and hung up. I'd like to know what she was smoking.
They called 4 times yesterday, when I was out of the office and my outgoing message stated that fact. They've called again today. Never leave any messages.
