Who called from 2135256871

Same as the above... i got a call with music in the background then they hung up after i said hello twice.

Got a call from this number.  I let it go to my answering machine but no message left.

called 08/04/2015 - 9:31 AM. I don't know anyone by the name: Name Unavailable. LOL. No message of course.

Call my home a lot.  The one and only time I have answered that number there was just silence on the other end.  I wish all scammers, evil doers, hackers for evil, would all be dropped in the middle of the ocean without life vests.

After a pause...
(in an Indian accent) Hello, this is the Technical Department, calling about your computer...
(Me) [***]. - hang up.
