I called back and they said that they are Insurance Link. If you asked for insurance quotes online and supplied a phone number, that is how they got your number and it would be considered a follow-up call, not telemarketing, if you ask me.
I don't answer my phone and this number doesn't leave a voice message. But if you want to put a little fun in your day, the next time you get a call you don't want, go ahead and answer it...act like you are really interested in whatever they are selling, but cut them off and ask them for their personal phone number, so you can call them back! It's only fair...they have your phone number, you should have their personal phone number. Then you can call them all hours of the day and night, sort of a "follow up" call.
