Redemption page responds a wrong feedback page

[serial-coder]

When a user commits redemption, the redemption page responds the following message.

"Your redemption request is in progress.
You can close this page and later check the status of PKTF token through your Ethereum Wallet."

such message should be used in case a user re-checks his/her redemption status only.

That is, in case a user commits redemption to each voucher for the first time, the redemption page should respond to a user with the following message with an estimate time asking a user to wait.

"Your redemption request is in queue and waiting to be processed.
Estimate time to complete your request is [XXXXX] seconds/mins.
You can close this page and later check the status of PKTF token through your Ethereum Wallet."
