Unknown Caller - The calls are coming from Aurora, Maine and Sanford, Maine. The woman says there's no problem with my account now, but I am eligible to lower my interest rate; my eligibility expires shortly. No mention of what kind of account this is, etc. I have had previous messages from a similar number (207-584-6937 which I reported earlier). My sister in another state also gets these calls. She has pressed 2 as indicated to stop the messages but they just continue calling. I don't answer at all.
