I get constant calls from this number 408-899-5372.  They just call and hang up and call at very late hours (after 10:00pm).  When you call back the recording says "Please 1 to pay for a debit card".  Yah, really, I'm going to give you my debit card number without even knowing who you are or why you are calling.  Get a brain dude....  .....   ....
