Tata Cliq — Fraud Company...

There was a sale on tata Cliq, we ordered and it was confirmed. But after a week, they called us and said we can't deliver your order... How stupid.. We ordered because we had trust on them as it is of tata.. but didn't expected this from tata.. we were waiting for our order but then they said we will not deliver... If they don't want to deliver or sell at low price, then why they post such deals on their app and make us fool? take action plz...
