They called asking for my son, I asked them to state their business, the woman said they were conducting some kind of "research survey"    I told her he wasn't available, she said she'd call in a week.  I asked if she had dealings with my son, she said no...then when I said don't bother calling back, she said she HAD to talk to him....I said: NO! and hung up....

Same experience. They call repeatedly, never leave a msg and when I called back it said the mailbox is full

this number has called us repeatedly over the last week or two...multiples times a day. i also tried calling back and got a recording stating that the mailbox was full.

caller id says "wireless caller."  The one time I did answer, the call was disconnected.  Calls around 1 p.m. everyday.  Tried calling the number back but receive a recording stating that the mailbox is full and cannot take new messages at this time.
