Who called from 9257380265

Caleld me at work.  No one there when I answered.

The number constantly calls our work place, often several times a day.  We don't ever answer because we don't know anyone in CA that would be calling us   here.  When the answering machine picks up, the other end is silent...we figured if it was that important, they would leave a message.

Received four calls in three days from this number, 925-738-0264, 925-738-0256, 925-738-0263.  No voicemail, no answer when I answer

i get calls 2-3 times a day from this number,they never leave a message ,i dont know anyone from this area code

got several calls from this #.  they so say they're washington mutual and when i say i don't have an account they tell me to verify the last 4 digits of my social.  i said absolutely not--hung up but they keep calling my cell.
