I tried several times on the toll free number of Data Wind company. But no body is picking the phone. Why?

Why they have poor customer support?

Why they are not responding phone calls of worried people?

I have sent money to the company and now I want my money back. It is not fair. They are just kidding on us and not responding on the toll free number.

If they planned not to respond anyone on the toll free number then why they set up this number?

I am waiting for my tablet and I booked it in the month of January.
