No, they don't appear to know yet.
But if you get out your statement from around the time you came off the fixed rate, you should be able to work it out. It's 12% of a writedown plus roughly 4% in cash.
Brendan can I just confirm the 12% is an amount paid off the mortgage not cash? For those of us whom have sold the property how does that work? Will we get cash? We just sold in September 2019 couldn’t hold out any longer!
