Who called from 2132135994

Called here at 8pm on Saturday night. Caller ID said "Security." Didn't answer. No message left.

Am traveling abroad, was awaken by the call on my cell at 1am. Didn't recognize the number, didn't answer. The number was preceded by +00, like this: +002132135994

Keeps calling at all hours of the night or day. 2132135994 please have this stop.

Call blocker might be of some help.  Also don't pick up on numbers you do not recognize, or where there are caller IDs that seem odd.  Or where there is no caller ID.

I pressed 1 for calls to stop a month ago and still get calls.
