Thanks @Vidula Khanna​ , but that won't be necessary anymore!

However the whole process is really weird. I received an email for an event I didn't sign up for (I checked all my emails for overlooked signups) so I thought that was the "email" I was expecting and then filled out the survey, but today I received the email for the event I did actually attend so I filled out the survey again.... I just hope that the first survey I took (for the event I never attended) is invalid, just in case!!!
