I've got a blank call followed by a missed call from +1-309-361-3731. Can anyone highlight what's the matter? Who is this [***] [***] calling from abroad? What should I do if I get this type of fictitious call in future?
they call every two days talking about received 2 free boarding passes and when you ask for the do not call list they hang up. they also use number 360-460-5570,
