This is a telemarketer who deals with mortgages for people who are having financial problems. I have gotten at least 50 calls from this number. The last time I pressed one and "Sean" answered. I told him I wanted to get off of their call list, and he never said anything and hung up.
Requests that you punch numbers to get off "their" do not call list but confirms "you've been removed" after a few moments whether your number has been entered or not.
