MagicJack voicemail again

I've had Magic Jack for years now & no longer use it on a house phone. I use the iOS app on my Ipod Touch. For well over a year it worked just fine then I started getting calls that the notification center said were "missed calls". I called myself on the house phone and it went directly to voicemail but the ipod kept on ringing. I got into a live chat & was upgraded to a senior tech. Time after time he and I tried turning off VM completely on the site to no avail. He got frustrated and typed that their web servers were down and not accepting new settings and just closed the chat on me. The thing is that the delay was set to 30 seconds & it was going to VM on the very first ring before all this discovery. I am thinking there is another variable involved here & just want them to fix it but still not working.
