Who called from 4048916683

I received a call from this number 408-418-5657 I don't reconize number let answering machine pick it up and it hung up didn't leave message.

They call and state something about subscriptions.  If you want your phone no. removed, they tell you to press a no. How they get unlisted numbers I don't know or even cell numbers. Annoying and just plain dumb.

Sorry. That should have been WCA instead of WCS.

I got a call this morning from SVC legal WCA  no message was given but the number was on my caller ID as  408-418-5670.....

I got a call from SVS legal WCA and I do not know what its about so I did not call back
any solid info out there? How do they get unlisted numbers? Thanks
