I have received email from the HO below. Should I respond or call them. If I don't, would they make a decision and return my application fee? Thank you.
"Dear [Applicant name],
Following your recent application for citizenship, you should have enrolled
your biometrics (scanned fingerprints and photograph) in line with the process
set out when you completed your offline application.
You were previously issued initial instructions on how to book an appointment
and enrol your biometrics within 45 working days.
This notice is to remind you that biometric enrolment is required within
45 working days of your application date. Please note if you have
booked an appointment after this date, email with confirmation receipt
from our service provider to this email.
You must now return to your online application to book and attend an
appointment at a UK Visas and Citizenship Application Service point to
provide your evidence and enrol your biometrics (fingerprints, facial
photograph, signature).
When you book your appointment, you will be advised what you need to bring
with you.
If you do not attend an appointment and enrol your biometric
information your application will be rejected as invalid. This will apply
even if you have provided all the other relevant information, evidence
and payment required to validate your application.
If you are under the age of 16 you must be accompanied by the
responsible adult that you named as part of your application. If you are
not accompanied by this person your enrolment cannot be processed.
You and your parent/responsible adult must provide an acceptable form
of identity; this must be a passport, photo driving licence, national identity
card or a UK Biometric Residence Permit. The proof of identity will be
checked against the details given on the application form.
