This is a voice-recording in Spanish. It says "You've been selected to win a trip anywhere" blah blah. I have very very VERY little tolerance for telemarketers and my line is (so I thought) clear of them. Now I get this call and I called back but "Backservice" is not available (they disabled it with their provider).

I did a reverse lookup (black pages) and nothing at all came up; not even the name of the Service Provider. Google has nothing either. I cannot tolerate telemarketers and will do anything possible to get more info on this number.
