Anyone been through a Carers' Allowance Overpayment First Tier Tribunal to appeal massive bill?

Ours has just been scheduled for late August and we have no idea whatsoever (apart from the short paragraph of standard info, which doesn't tell us much) how it works, what happens on the day, how to prepare, etc.

It would be so helpful to be able to talk to someone who's been through it for their experiences and thoughts.
