Who called from 2102808096

I just got called and hung up on four time's

I got a call today in Switzerland 210-280-8096! Didn't pick it up. No message.

Just got a call from this number, the lady stating that she were with a "Research Group" from Luxemburg, Euro.
Her english was heavily accented asian. Furthermore, as I'm located in Austria, a true luxemburgian would have tried to talk to me in german.
So I hung up.

Asked if number was correct & asked who was calling & she said some pharmacy. I told her never to call this number again. We shall see

This number appears on my caller ID several times a week, almost daily.  I have relatives in Tex. but not this number.  I called it back and it states no longer in service.  I don't want these calls again.
