Who called from 8168263037

My message was from the Local Firefighters and Paramedics but I assure they are not associated with these people. They say they are giving to burn victims.  I really have doubts about how much goes to burn victims etc.    I just hung up.

This number keeps calling me they never leave a message and when I try to call back it says it's not a working number. They been calling like 8 times a day sometimes.

Keep getting calls from this #. They never say anything and then hang up.

Lots of calls throughout the day. No one speaks & they hang up when I answer. I call back & it says the number doesn't work.

Have called every night for last 3 nights.  Just silence and then they hang up.
