Purchased nettalk due WIFI from BESTBUY and activated it on Oct2. i had to provide them with credit card info for "renewal". On October 5th, I noticed that calling the number assigned to adaptor produces "not assigned" message.
Since then I have trid many time chatting and email communication requesting them to fix the problem unsuccessfuly.
Finally I decided to return it and wright a report, hoping others read it, which might prevent them from going through similar experience.
