Tea anyone?
Milo, seriously, get some advice.
The fact it was wrongly addressed means you should be in a better position to pay them back on your terms, you'll lose this position if they end up taking you to court.
The Tax office once tried to hit me with a £10,000 bill because they sent my paperwork to the wrong address for 3 years. I was on benefits at the time and had no money.
Before I got good advice I had been told by the Tax Office they would only accept I pay the money to them first and then request a rebate because of
their error.
W*nk*rs.
