Who called from 3604743263

Caller ID says S Service Info.  When I answer the phone, the line goes dead.  I tried calling the number and got a recording stating the number is a non-working number.

Did some further investigating and found out it is a telemarketer.

Called, asked for my then hung up.  8:30PM

Calls at least twice a day, every day, no message, sometimes a grunting sound. This has been going on for three weeks.
