If you are not prepared to give it on 28th jan, then you will have to get a new voucher.
You cannot, only if the expiry date is 28th jan. But if it is your pre-scheduled exam date, (but not the expiry date), you can extend it up to the voucher expiration date (printed on the voucher). You should contact your local prometric test center for this.
However you cannot extend the voucher expiration date.
:idea: If you really need it, try to sell the voucher.
