calls from this number are frequent.  I answered it once and they started talking very fast about mortgage.  I told her that I was not interested and hung up.  Now the calls are persistant.

they are trying to sell you spam stuff
mtg rates at an all time high.......I hung up its all automated

Calls one of our phones at least once every 3-4 days for the last 4 weeks.  No message ever left.
