Just 510-727-5730 appears in my caller id. I blocked the number a few weeks ago but my phone will still ring once before disconnecting every time this number calls. Typically, I get several calls a day. Anyone know who this is? I am surprised no one has reported being harassed by this number yet. I am guessing it must be some collection agency calling me about someone else's debt. I seem to share the same name with someone who doesn't pay their bills and b/c my name is the same I get calls like this all the time. Anyone know for sure?
