Guarantee its a scamming technique. You may have an unlisted number, but that doesnt mean you number is safe. Even if you enter your number into a do not call (DNC) registry, that doesnt mean that you number never appears on telemarker lists. Telemarking companies are required to check against the DNC list, this prevents lawsuits... but that doesnt mean that someone else cant just acquire your number and call it, it costs a lot of money to get the list.. but even more to get the DNC list (around $14k).
I can understand why people pick it up, who knows who it may be. but by pushing numbers on their automated carp thing, that just signifies to them that it is a valid number, or even worse, just by picking it up.
then can turn around.. and sell that list, if they want. who knows..
i googled it to find out who it was too... this is probably the 8th time i have gotten a call like this. i picked up once.. same thing, Spanish speaking. immediately hung up.. but the damage might have already been done.
Got the call last night at 8:53pm EST at work (unlisted number). A guy left a very brief message in Spanish which my company's phone system recorded and emailed to me. I still have it in case anyone's interested (email me at [email protected]).
