How do I reschedule or modify my exam booking?

[HS1]

Hi All,

I have booked my RHCSA exam but now have been informed that I will be out of the country on my exam day. I can view my exam booking and other details when I log in to my learning portal but it doesn't give me any options to change, modify or reschedule my exam booking. 

Can anyone help?

Many thanks in advance.
