who is this

It's a Vonage marketing call

left an unknown voicemail. Didn't call back

they continue calling 5 or more times a day i really want them to stop

This is Vonage calling to try to get you to switch to them.  I told them if they want me to switch to them, then they can pay my phone bill.  The girl got smart with me and I told her that I wasn't the one calling to get me to switch from the company that I'm happy with to a company that doesn't offer half of what I get with my present company.  She hung up, but I'm still expecting another call.  Guess I'll have to get belligerent with the next one.  These people are a pain in the butt and call you even though you're on that joke "Do not call" list.  What a waste that is......
