same here -> Missed call/ no message.. call # back it's busy- I see a few notes that advise it's a call trying to sell cruise tickets. I also see notes trying to blame your phone companies?? really? These call centers use auto dialers that dial numbers in sequence. Doesn't matter what phone company, or if you block them because they usually have a bank of numbers through a trunk system.Doesn't matter if you're on a do not call list either- they're not using a list. Just keep reporting the number until they shut the whole operation down...... .......... and then it pops up somewhere else again...
