Omg that is insaneI have had a reply from the immigration office.
They have made up some nonsense saying my biometrics were refunded 2 years ago (2 YEARS AGO!) , despite confirming receipt of my biometrics by email. They can't provide any evidence of the refund. I have no refund on my account, and no cheque came through the post. I also received no correspondence from their office saying their was a refund.
I have now paid for a second biometrics.
Even my local MP's office are blown away by the incompetence. I will be going to the media with this nightmare. I've had enough.
