Newcastle United have been accused of a "dereliction of duty" towards their supporters after not communicating season ticket plans.
The Newcastle United Supporters' Trust (NUST) sent a letter last week asking for confirmation of refunds, with games set to be played behind closed doors.
It also wants season ticket payments for the 2020-21 season to be paused.
Most top-flight clubs have said they will refund or credit season ticket holders for behind-closed-doors games.
Newcastle are yet to announce plans, and did not comment when contacted by BBC Sport.
