Who called from 8185561985

Have received several calls over the last 2 weeks, no message, and "you have reached a number that is no longer in service" when I call back.

i received so many calls from this number. but when i answer they hang up. so i call back. everytime i call back the number is no longer in service so i blocked this number. it's quite strange.

8/01/16  10:27 PDT  This was apparently first of 3 calls that came in while I was out.  ID is unknown and no message left.  Have added to blocked list.  Not in the mood to deal with this garbage.

A call came in from this unknown # on 8.8.16 at 4 pm. Blocked after reading earlier posts.

Called Thursday, 8/11/16 at 11:47 am PDT.  Caller ID showed "Unknown Name".  No message left when answering machine came on.
