Is it mandatory for a disabled person of the 3rd group to pass the VLC if he cannot be mobilized?

Received a summons to the roadblock, since 2007 he has been removed from the military register (disabled of the 3rd group, labor disability). Do I need to appear at the TCC? There is another nuance, in the summons my last name is indicated incorrectly.

What is my procedure for obtaining a UBD certificate if I have already resigned from the service?

Is the MSEK certificate valid if the surname is indicated on it as a maiden name? Is it necessary to change the disability certificate in connection with the change of surname?

Where can it be restored? Tsnap or passport office? I have a passport.
