Who called from 3023946888

I got the same "I'm sorry" and hang up this morning from a male voice.

got the same message about lower interest rates

Also got the male voice saying "I'm sorry" followed by a hang up!

Got the I'm sorry and then hang up. I called back the number, was a telemarketing firm. If you press '1', they say they'll take off your # from their call list. They want you to input your 10 digit # after the beep, but there's no beep...

I got the " i'm sorry' and then i had to hang up... should I be worried about the fact that I answered?
