and here its not written about the expiry of the voucher.
I wish what you assume comes out to true.
Better send an email to the one who send you the voucher. Since the purpose for the voucher is for you to take SCBCD 5.0 due to the poor testing environment, it makes no sense for a long validity period. But it is also too troublesome to distingish the voucher for you and others, so, normal case should be applied.
Anyway, just check with Prometric.
Well... Amand, all the best to you in the new test! Go there and win this certification
Since in the email they have not mentioned the validity the voucher can be used anytime.you have unlimited time.use it.
all the best.
still if you want you can get it confirmed
