oh! thats intreresting! the same nummer calls me twice. but nobody was on the line.

oh,thats really interesting,this number calls me too (three times)

Calls me twice a day! Who is this?!!!

Had more than 5 calls a day… Started almost 2 weeks ago.
When I call back, an automated message sais that the “as we could not reach you recently, o2 Team will try to call you back later”.
I called o2 support team, they had no need to call me neither they know this strange number…

it´s O2 Telefonica
