Who called from 4018459998

Pretty much any number with 9998 seems to be them. Suspiciously I started getting these calls after I associated my number with Facebook which really annoys me that Facebook decided to give my number to a telemarketer or surveyor if that's the case.

same as above, 2 to 3 rings and hang up. no message left.
when i did answer on first ring no response

they also called me. I called it rang once and it said service is disconnected

This phone number keeps calling me.  I answered once and they hung up.  They call me while I'm at work, while I'm in bed, just all the time.

Just called me. Returned the call no one picked. They keep calling at midnight.
