Biometric Letter won't scan

[hood]

Hello house,
I wonder if anyone has come across this before
I took my 2 children to post office on Thursday for Biometric enrolment as I filed in application for MN1 under section 1(3). The younger child biometric letter won't scan at the post office for unknown reason, so I was advised to contact home office which I'd did. email was nationalitybiometrics@homeoffice.gsi.gov.uk
Has anybody experienced this before? and was the above email the right one
I also read online that once the first letter fail subsequent letter sent by home office will not also scan how true is this
Please I'll appreciate some thoughts from members
Thanks
