With any proposed adverse actions always read the entire letter the VA sends. On proposals you have 30 days to request a hearing and the VA will not, (should not), reduce the benefits prior to the hearing. If request for hearing is received after the 30 days, then a hearing will still be held but the final action can take place prior to the hearing. During this Covid period if a hearing has been requested after the 30 days you can request a "skype" formal hearing which are recorded and transcribed. As far as repaying anything, letter that proposed the severance should have advised you of this if that was what they were planning to do. Something like "this may create an over-payment".
