Virgin refunds aarrgghhh!

After my involuntary downgrades back in December x 3, and after signing under duress that I would accept a 75% refund on my 'select voucher' virgin are trying to palm me off with miles saying it's not cash, it's £250 towards a - surprise surprise - virgin flight. Funny that it doesn't state that on the voucher I signed. It clearly states 75% refund, credited back in euros, usd or local currency, paid via transfer or cheque.
Has this happened to anyone else? I'm sick of chasing this. I wish they could actually read what I signed rather than fob me off. I have a copy in front of me, they have the originals.
