Misguiding the consumer

They have an unlimited calling plan to India for $26/month. In the front page they have listed in bold that this is an unlimited calling card. I have also talked with their officer and they also said this is an unlimited calling card. But the reality is they have a cap of 90 minutes/day on this plan and they did not tell clearly that there is anything like this. I think this is extremely unethical and right steps must be taken against this company for misguiding the consumer. There are only somedays on which we talk for 90 minutes. And it turns out that the actual cost of calling is 4-5 times more expensive than the other calling cards - Airtel and all the other LD calling services.
