Who called from 4423336299

Called my 800 number - there was no voice on other end.  Recalled the number and got message "The number you called is not in service".

Called my 800 number very early in the AM  Sleepless nights!! Many other numbers are doing the same thing.  We have a 24-7 emergency line right next to my bed due to the nature of our business and I must answer all calls.  No one is there when you pick up.  This is getting maddening. Too many sleepless nights. HELP STOP THIS PLEASE

I have the same issue as Cathy.  In morning.  I have this and about another 15 different numbers.  This all started about a month ago.  All calling in middle of night.  Cannot return call to any of the numbers.  Would like to find out how to stop and why it started
