This Number calls my mobile phone every night from 4pm to about 10pm so far. It never leaves a message and had been calling everyday for about a week. I would love to know who this is.

I've never answered it.  They call every afternoon, never leave a massage.  Been going on for a few weeks.

Calls from this number come in around 8pm. It's most likely the alumni association or some organization at UC Berkeley asking for donations. Screw that Berkeley, you've already taken enough of my money!!

Screw that..Donate to Cal you cheap [***]

it is the cal calling center...just answer and tell them to put you in the "no call list"
