Student Finance, Home Office Checks

Hi,
I submitted an application for student finance on the 04/02/2024. I've sent all documents requested of me by the student finance, all original biometrics, birth certificates and all. I've got an indefinate leave to remain, which started on the 4/01/2024, previous biometrics from 2021 to 2024, was all sent. I phoned student finance to check on progress of my application, only for them to tell me they waiting for home office to confirm my residency for the past three years. I still do not understand why, as all original Biometrics were sent. I phoned the Home office, an advisor told me there's nothing they can do, as they can't send any proof of residency, I should send the ones I have got to student finance. I'm really stressed, and don't know what else to do.
