Who called from 2142860215

Have two calls from this number over the last two days.  No messages left during either call.  Return calls cannot be completed.  Would love to know who this is, and why they keep calling.

This number has been calling me for the past two days and everytime I try to call back it says that the number is out of service

Same is happening to me!

Have gotten 2 calls from this number in last 24 hours, but they left no message and can't call them back. Very strange.

That number called me and when trying to call back it says discontinued number
