Dallas Technologies is a hub of cheaters. Its a fake company too check in google.If you join as a trainer then initially you will be treated well while you join as a Trainer.
Then once the batch is completed you will be running behind them for the money.They all are trained to cheat people. Mostly they will not pickup your phone. If they pickup.then you will be told stories to avoid the payment.
Some of the name of the cheaters are Poornima Pinky, Prabithra, Mohammad, Shalini etc.Not sure why police not taking appropriate action against them.
