I did not answer the call, just let it ring.  The phone must have ringed for five minutes- a new level of rudeness.  I thought the phone companies had a ring limiter?

Got a call looking for my mother in law for an interview, saying she is from the bank. I called back quite a few times, but it is busy.

get missed calls from this number a few times a month. No messages are left. I am on a do not call list.

at 7pm caller phoned again, but left no message this time either.

recieved a call requesting info on a recent TD Banknorth transaction. Caller identified herself as "Paris". I told her my name was "London" and hung up.
