Unocoin had a toll free number where you can communicate if there is any issues with your account and by reading your thread i did not see you doing that ,why dont you try contacting them through their toll free number and settle the issue as you wont be able to see their response from the unocoin team till now in this forum.
I did call them every alternate day when the issue was open coz they never responded on their support ticket system.
The issue is resolved now.
After the funds were received they suggested the problem was at my end. However I didn't face this issue with other service providers.
