Hi @RenukaA,
that's just for these days because between 2nd and 17th November there's an exam facilitator switch:
KB0013209 |Transitioning from Webassessor to Pearson VUE FAQ
After that, no vouchers will be issued anymore, existing ones that are not expired can be used but with Pearson - see the 5 min video in the link above it will explain you how to get it.
If you go to your SN University account, there will be "My exams" tab:
It's not yet available, wait until the end of next week and meanwhile check the video to understand the new procedure.
Have a wonderful day and good luck to your exam!
