Lingo is selling "Unlimited" calling plan but they actually lie. They limit the calls to 5000 minutes and on top of it they have hidden residential usage requirement that limits your calling number to 6. However, they have suspended lines of 3, 500+ customers for using over 500 (yes five hundred) minutes leaving them unable to call 911 in case of emergency. They put customers lives in danger. Many have reported this company to the FCC, FTC, Attorney Generals office. There is lawsuit against this company for this fraud and they soon will be shut down. And it is highly likely that the company owners and managers will be in jail, like the Enron fraud.
Their customer service cannot be worse. You must stay away from this company.
