Who called from 2533829008

I keep receiving calls from this number... sometimes 3-4 times a day.  They don't leave a message and when I tried to call back, I got a recording saying to press 1 if I want them to stop calling.  That was 3 days ago and they keep calling.

Constantly, 3-4 times per day over past two weeks, but not on weekends, getting calls from this number.  When answering, no is there, silence for 3-4 seconds, then disconnects.  I have reported this to the Do Not Call Complaint Registry, but calls continue to come.  What can be done to stop this intrusion of privacy?

please do not call me

I received a call from this number. They hung up when I answered the phone and when I returned the call the line was busy.

I receive calls from this number several times and when I answer they hang up or if I don't answer they do not leave message.
