They hung up

Recently I had the same problem with this number, My provider is investigating this number. Contact Comcast Xfinity for  info on this number 856 283 4512..Somethings very fishy about these calls, and they hang up abruptly when I answer. My provider had to block this number from my phone and computer..

Report this number to your telephone company or provider, my provider had to assist me in blocking this number from my lan line and computer..You're right when you answer they hang up abruptly
