Revolut freeze locks couple out of £37k house deposit before completion

A couple is approaching completion of a property purchase. Revolut froze the wife's account during what it calls a "routine security review" over a week ago. No documents or ID have been requested yet, but the freeze has restricted access to their joint savings account holding a £37,000 house deposit. They have given notice on their rental home and are seeing direct debits bounce, with concerns about their credit records.
Have you ever had a bank freeze cause a real-life problem like a missed payment or delayed move?
