Who called from 4252338877

i recieved 4 calls withibn a hour they did not leave a message or anything

Just got a hang up from them. I answered, no one said "boo". VERY UNPROFESSIONAL.

This company calls 2 to 3 times a day.  If i answer there is just dead air. If i do not answer there is no message left and they will call right back.  Who ever this is or what ever company it is needs to get better people.  This is unprofessional and rude.

I am on the Cell-Do not call list, and this number has called me 4 times in a 3 hour period.

Called three times a day with no message for the last week
