City Fitness misleading fees refund?

I am one of many New Zealanders who were overcharged by City Fitness with their mandatory 3% processing fee.

I just read an article in the NZ Herald which said "At the sentencing hearing, commission lawyer Jacob Barry said that as far as he was aware none of the money had been returned to customers, the NZ Herald reported. The gym’s members can still seek refunds, including through a class action."

Has anyone heard anything about this or tried to get a refund?
