Looking for another provider now

Two points why I would not recommend them:
Upon sign in they charged me $152.88 by mistake. I supposed to pay $10.99/month, so I requested the explanation by e-mail.
BTW, I didn't find any way to call AXVoice support.
They responded that transaction will be refunded. That happened a year ago and I still didn't get my money back. AXVoice has been charging me for $10.99+taxes and fees for entire year, but $151.88 got lost. For last two months I didn't get any response from them to any of my e-mails...
Second issue: some of phone numbers, that I was dialing too often, stopped working. For example, my company PBX access numbers stopped working one after another. As soon as I was switching from one access number, that started giving me a busy signal after a month of using it, the next one stopped working in a month or so. When I lost an access to the first one, I've sent an e-mail to support: no response at all... Finally I came to the situation that I couldn't call any of my most used numbers and the account became completely useless.
