I have been getting calls from this same number and we are also on the do not call list. They never leave a message. I would like for them to stop calling.
Caller Id said Franklin & Marshall College, which is indeed in 717 area code (where I'm originally from), but caller identified herself as "Athena" and asked for my fiance. She sounded very young. I said he wasn't here right now: asked if she wanted to leave a message. She said she'd just call back later.
