I have signed up with Lingo for a 2 year contract for a plan called "Lingo World Max" unlimited calling plan. I have recieved the following email from them:

"Thank you for using Lingo digital home phone service for all your domestic and international calling needs.

We see from our reports and analyses that frequent calls are being made from your Lingo phone that are inconsistent with the normal calling patterns of a residential customer. For security purposes, we are sending you this notice to inform you that if this calling pattern continues, it poses a risk of violating Lingo’s Terms & Conditions, which can be found at www.Lingo.com.

If you believe your future calling patterns will remain consistent with your current use of the Lingo service, we would like you to consider switching to another Lingo calling plan, such as our South Asia Plan (just $29.95/month with unlimited US and Canada calling and a low 2.9¢/m rate to both Bangladesh and India!).

Our systems will continue to monitor your calling and usage patterns for conformity with Lingo’s terms and conditions of service. If you have any questions regarding this notification, please contact Lingo Customer Care at either [email protected] or 1-888-667-4281.

We thank you for your cooperation!

Sincerely,
Lingo"

I have just checked my minutes usage and for the month of March (3/13/2010 - 4/12/2010) and I have used only 853 minutes. As I understand from other comments on this website and on the Internet, the next step is they will automatically charge me extra and if I cancel at that time, I will be charged with cancellation fee. So Lingo makes money either way by ripping people off. They do not define what constitues residential usage pattern / high usage pattern in the their terms and condition. I can not believe that basic consumer rights are violated in such a brazen way and nobody is doing anything about it.
