Biometrics Invitation

[SwiftDB4]

I mailed Form UKM application 24/2/25.
Credit card was charged 27/2/25 with what I think is a reference #.
No information from home office until reply to my e mail 11/4/25 that they are processing my application.
Still no Biometrics invitation, so e mailed off to all of these 25/4/25:
nationalitybiometricsoverseas@homeoffice.gov.uk
NationalitySupportTeamFMT@homeoffice.gov.uk
UKVIEnrollmentInformationUSA@homeoffice.gov.uk
Because I did not apply online, but by post is there a reason no Biometrics Invitation yet?
This is very frustrating getting ignored on Biometrics and I'm afraid my application will eventually get denied because no Biometrics.
Is it worth a phone call to +44 300 790 6268 or any other avenue to get an answer ?

These applications take a while to get a biometrics invitation. You contacted them already, give it a few days.
